Re-thinking the system

134.134.248.29

Posted on November 27, 2000 at 11:25:11
The longer I live with SACD the more I am convinced it should drive a re-thinking of what audiophiles expect from their systems.

First, the need to compensate for poor digital sources may be coming to an end. With reliable source material, many of us may really just now hearing our equipment clearly. I know that I am revisiting tweaks and room treatments as a result.

I have spoken with a number of manufacturers who talked openly about introducing euphonic colorations to try to compensate for digital limitations. We certainly can hear a huge variety of this in sampling just a few DAC's and CDP's.

Perhaps the most controversial is the idea that realizing DSD's true potential will call for wide bandwidth, high power/efficiency, FULL RANGE systems. Not to say it can't be enjoyed with less, but along with the lack of typical digital artifacts comes with some very interesting things happening at the frequency extremes.

Additionally, the ability to reproduce accurate volume levels, without typical digitial fatique suggests. I am constantly amazed at being able to approach realistic volumes without the shriek and buzzsaw effects of RB cd's.

It would be interesting for residents to talk about their experiences with what SACD is doing in their systems relative to basic re-examinations.

Just some thoughts on a foggy November morning . . .

A couple of observations from not-so-foggy Corvallis this morning...

Re the revisiting of room tweaks: I've removed my DIY room lenses after 600 hours of SACD-section burn-in on my 777. I no longer hear discernible differences with or without them when I play SACD's. Neither can my wife.

Re volume: I now listen at louder ("more realistic?") levels with SACD (my listening fare is classical and jazz). I'm enjoying it a lot more. And, like you, I hear no "shriek" or "buzzsaw," just greater timbral and dynamic accuracy.

It's the fun I got into audio for in the first place.

The room treatment thing makes perfect sense to me. Trying to tame typical digital harshness most of us have probably over tweaked or treated, just to get the glare down.

My experience with the volume issue is somewhat cautionary. Freed from the pain factor, I find myself looking over at my pre and being shocked at the output level. Seems like there might be some ear and equipment safety issues here, if we aren't careful.

>>I have spoken with a number of manufacturers who talked openly about introducing euphonic colorations to try to compensate for digital limitations. We certainly can hear a huge variety of this in sampling just a few DAC's and CDP's.<<

I strongly concur with the above statement. Many of today's top DACs and CDPs (why name names, it just pisses people off) are colored and smoothed over. Many listeners associate this type of coloration as "better" and "more analog-like"; a misnomer if there ever was one. This was my impression of "upsampling", such as it is, as well--overly smooth, but fake. But for people with problems elsewhere in their system, or with poor quality digital source material, such smoothness is interpreted as better, when in fact it's not. Spreading honey and mustard sauce on a Chicken McNugget makes it go down better, but it's still a piece of pre-processed chicken entrails. Or something like that :-)

The standard we ought to hold digital to, is to demand BOTH resolution AND a liquid, musical presentation. Unfortunately, most DACs and CDPs out there excel in one area or the other, but not both. That it is the promise of DSD--to finally meld the two honestly, w/o making compromises or introducing fake colorations or processing the data to playback something other than what's actually on the disk (i.e., upsamplers).

Rick,

Your comment on ear safety is well taken...though I'm not masochistic enough to push the volume to anything approaching what I can discern as the threshold of pain...certainly nothing louder than what I perceive that I hear in the concert hall...and that's acoustic music with very few exceptions. But your implicit point that the absence of typical Red Book nasties could "deafen" us to potential ear damage certainly bears repeating.

Ditto your cautionary note regarding downstream equipment, especially, I suspect, when running in Custom mode. In my situation, I've yet to detect any audible sign of hardware distress (e.g, clipping, voice-coil rubbing, etc.) though I'm running typically at higher volume levels in SACD. (Of course, I appreciate now that I had substantial power supply mods done to my line stage and amp just this year.) Time will tell, of course. So stay tuned.

After getting my SACD player and the format was so much better than CD, I decided to hook up my turntable. Analog stomps the SACD's into the dirt. Now I listen to records more than anything. Anyone one else notice this?

Sure the SACD player is quiet and has better bass dynamics. It sure doesn't beat an LP for timbre, soundstaging, immediecy and musicality. My system was SACD ready to begin with. Try horns and SETs if you really want to enjoy the music. High end DR speakers and complicated negative feedback amps don't have natural timbre and dynamics and compress the heart and soul out of the music.

Mike

 

Re: Re-thinking the system, posted on November 27, 2000 at 14:31:57
Rick,

I agree that DSD can allow one to upgrade their system since the source is so much more neutral AND dynamic. I find speakers that excel in dynamics (i.e. horns) can really showcase the incredible attributes of DSD.

Also, with greater neutrality from the source, silver cables can add another level of realism.

And finally, there are SET amps that can capture the increased purity in those new pits and when mated with horns, can deliver the "rockinist" sounds you would ever want!

What a problem to have, eh? :-)

How can this be? if this were really true it wouldn't have made a difference to begin with! An SACD player isnot going to change the acoustics of your room. Maybe you've been crankin in up so much you've lost your hearing? : ^ (

It's interesting that, based on a very small N, the feedback I get from people with horns is that they have been less impressed with SACD. Not sure what it means, just a data point.

I think your assumption might be in error. The Positive Feedback herd which has been unanimous in their praise for SACD tend to be historically pretty hard core vinyl/tube freaks, most with some pretty good TT kit (David uses Linn, I myself use Wilson Benesch).

I think we are in such a new time, that bold assertions that X tromps Y and the like really don't serve the purpose of open engagement.

Horns and ambivalence, posted on November 27, 2000 at 15:21:36
Rick Gardner


 
I confess to a certain ambivalence about horns, as a general catagory of speakers. I am seduced by the efficiency and dynamics, but put off by the colorations I continue to hear, and bass response issues (short of huge contraptions like the Avant Guarde Trios). But . . . some people who's ears I greatly respect (such as Steve Bednarski) swear by 'em.

I will continue to try to hear as many of them as I can.

I just read Jim's post and it specifically says that the room treatments that helped with CD did not make a difference with SACD. This is ENORMOUSLY different than saying sacd changed the acoustics of his room and can be explained by factors other than magic.

 

Common Practices, posted on November 27, 2000 at 15:24:59
Rick Gardner


 
I think it is fairly common practice for audiophiles to use tweaks and room treatments in lieu of tone controls. I don't think I am alone in this. Damping down a room to control brightness can, at some point, significantly alter the tonal balance of a system. Nothing magic here . . . but interesting to see how the discussion turns to agendas.

I think it is very interesting to explore how a new medium is being experienced through different systems, and from differing points of orientation.

As I said, I have picked up a very thin thread (admittedly) about horns and sacd. It will be interesting to hear from additional users as the installed base/experience with SACD grows.

My only concern is that it is very early for blanket pronoucements. I would preferable to avoid the whole warring camps thing that too often characterizes audiophila.

I also have room tweaks which include damping.

I use them to control room resonances - NOT the tonal errors of my source components.

If his room was coloured prior to SACD, then it remains coloured. If his original source component was terribly bright or bass heavy then room damping was not the proper fix in the first place!

Not really, digital home playback is 25 years old! We are talking about current digital versus LP's right? What we have is what we have.

"I would preferable to avoid the whole warring camps thing that too often characterizes audiophila"

Forget it Rick, that will never happen. It's because we are all humans (I think) and we like what we like, and as in the past, we will argue endlessly till death.

Just what I thought, you have a WEAK argument.

He proclaimed:

"I've removed my DIY room lenses after 600 hours of SACD-section burn-in on my 777. I no longer hear discernible differences with or without them when I play SACD's. Neither can my wife."

The room lense WILL PERFORM THE SAME WETHER THE SACD PLAYER IS IN THE SYSTEM OR NOT. The 600 hours DOESN"T CHANGE THE ROOM ACOUSTICS! He claims that when he REMOVES the room lens NOW he can't hear a difference. This tells me THE ROOM LENS doesn't work, or he has had a change in his hearing sensitivity towards the worse.

Hi Jazz,

You read my comments right. Here's what came to my mind--and since
I'm neither a recording engineer nor an acoustician, it's FWIW
speculation:

The lenses in my setup primarily affected image specificity,
palpability, and location. I suspect that conventional CD brick-wall
filtering and associated glare and grunge affect not only the quality
of what we hear, but also the (virtual) physical portrayal we
perceive. Substitute the essentially non-brickwalled bandwidth
characteristic of CD, and you allow instruments and voices to
"break out" of the Red Book cocoon...and in doing so, put them in
proper spatial and three-dimensional as well as tonal perspective.

Whatever the explanation, imaging, etc., snapped into focus in SACD.

I've never used room treatments, so i have no observations to go by. but your explanation strikes me as one that can be supported by simple wave properties and the measurable and audible differences between CD and SACD. Certainly there are analogous though not identical differences between CD and vinyl.

 

great thread......some thoughts, posted on November 27, 2000 at 19:48:27

very entertaining thread,

does sacd cause you to want to change system setup?

i think; yes and no are correct.

if your system is not properly setup; it won't be right for either cd or sacd. if it is dialed in for cd; it will also be good for sacd.

but......

if your listening habits change with sacd some minor re-tweaking may optimise performance and this is my expierience. with cds i was very concerned about reflections. i used tube traps in certain places to control these reflections and as a result the imageing improved; more depth, more body and presence. also, these tube traps reduced the digital harshness sometimes present on cd. my system was tuned to optimise cds as that was 75% of my listening. i didn't need the level of control for my analogue; but it still sounded good.

now, i am listening to 25% sacd and 25% analogue. so i have made some adjustments. i do listen to both sacd and analogue at somewhat higher volumne. so bass control is slightly higher priority. imageing for sacd and analogue is naturally much better and the reflection control is not as neccesary to attain excellent performance. also these formats benefit from a slightly more lively room as the nasties of cd playback are not in evidence. so i have moved my tube traps to maximize bass control and increase room energy.

a previous thread talked about how your ears adjust to sacd and you learn to listen differently. i have had that expierience. i think that when many of us talk about how long it takes our sacd players to break in that is partially because after the machine is done breaking in we are still breaking in.

in my new setup cds still sound pretty good. i don't know if i am different but for whatever reason it seems fine. i do generally listen at lower levels with cds.

i am no expert at acoustics but this is my expierience. over my 6 years as an audiophile i have constantly evolved as i have listened and learned. i made no major changes with sacd; but i did change the balance slightly.

happy listening!

I agree with the idea of re-thinking of all the rules for domestic audio reproduction with addition of SACD into our universe. I would like to say about my experiences with a higher quality source.
Cables are now 100% as a equipment pieces.
Room acoustics are now maybe more then 50% of what we hear.(without any comments...)

Re: Agree with Rick Gardner, posted on November 28, 2000 at 06:16:57
Hi Rick, I have had similar experience with SACD as you have mentioned.

The output level on my pre-amp is higher than before, now minus that digital glare. It is so easy to keep pushing it up, but we all got to watch it if we are to have prolong listening pleasures.

You are right to say that a number of manufacturers intentionally introduced euphonic colorations to try to compensate for digital limitations. How else can we can hear such a huge variety of sound characteristics in DACs, CDPs, amplifiers and speakers?

I suspect that a lot of us have been guilty of over-tweaking or accoustic treatment one way or another in trying to tame typical digital harshness and to get the glare down. That explains why since the dawn of RB CDs, the world have seen a renaissance in the popularity of tube-amplifiers. Certainly, the reasons often cited for using a tube-amp is always that it sounds more "musical", "more sweet and warm" but never more accurate or precise. Don't you think people should listen to music "Just the way it is"? The best tube-amp should sound like the best transistor-amp. Anything else is additional stuff that's not meant to be there in the first place.

Sadly, even with the advent of Hi-Rez audio formats like SACD and DVD-Audio, the urge to tweak and re-tune to compensate for perceived "unmusicality" will not come to an end just yet. I wonder how may of us here are really hearing the true potential of these 2 new digital formats to comment on them impartially. Even now, we hear debates going on on which are the more "musical" SACD players.

Your postings are a breath of fresh air, worth pondering about and I take your recommendations for quality SACDs confidently.

I was lucky to get a copy of Spitball through a friend of mine, I thought it sounds terrific too. I will get the Jennifer Lopez and Joe Satrianni soon. Dave Brubeck's Time Out is out of stock within a week of its arrival this month.

Thank you

I agree, to some degree. I think we are dealing with more subtle effects here, than simply overt inbalance. Let me put it this way. I am more comfortable in "opening" my room (removing damping) with SACD than with either analogue or CD. My subjective experience is there is simply a much higher level of focus with SACD, which especially keeps high frequency sounds more closely aligned with their apparent source, avoiding that disconnected "hash" we all object to.

Actually, we would all probably do a lot less tuning and tweaking if we had usable tone controls.

Pardon Me ... why did you proceed in mis-quoting me. You link your statements as my own - then you answer yourself!!!

My only TRUE quote was:

Your reply:
>>Actually, we would all probably do a lot less tuning and tweaking if we had usable tone controls.<<

Tone controls do only one thing, they amplify or attenuate frequency sections - they DO NOT damp or control room resonances.

Room acoustics should have nothing to do with your equipments inherited problems. In other words - if a Concert Hall has bad acoustics do you tell the Band to lighten the bass or lower the guitar volume in order to achieve the correct tonal balance OR with do you fix the Hall for proper acoustic portrayal.

Certainly - I would prefer to fix the Hall(Room) - instead of playing with tone controls or changing source equipment to suit my rooms poor acoustic characteristics.

Whats more laughable is the notion that after 600hrs of 777's break-in suddenly the room display even better acoustic qualities.

Are you kiddin me!!!

>>I was referring to a phenomena where, whatever the content of the original post, some respondents manage to twist it around to continue to assert positions clearly articulated by them elsewhere (e.g. the whole, 777 sucks as a CD player {my hyperbolic illustration}<<

I have stated many times - I liked the 777 player - but I am against such propoganda that claims the 777 as a GREAT CD 'giant killer' and a sudden fix for room induced distortions (amounst other insitefull but ludicrous happenings).

My agenda is based on reality, not the "hyperbolic illustration" put forward by many sacd 777 advocates!

I read it Jim. I got it the first time I read it. Take out the 600 hours. Now why doesn't the room lenses effect the sound in the room anymore? Did you move your speakers?

My intention was not to have a drawn out argument. I just see no logical reason why the lenses worked before and they no longer effect the sound. I mean they must have made a difference before:

 

Re: Re-thinking the system, posted on November 28, 2000 at 08:11:31
If you are into Horns & SET's I can see where you wouldn't appreciate SACD's superiority over any other Musical format to date. An SET amp is just a low powered expensive non adjustable tone control. The only benefit is that with horn speakers, which I have experimented with, Is that it it covers up some of the harsh horn colorations & distortions. If you like that type of system, fine but don't disparage & try to evaluate an accurate source of music reproduction on it.

Yes, they made a difference before. And now they don't. If you want to attribute that to bad ears, be my guest. (Of course, you'll have to include my wife as well in that assessment...and her hearing, at seven years younger, is admittedly better than mine...which is why I have her check out any major alterations I make to the system.)

I'm not out to repeal the laws of physics, simply to report what I've heard. Rick's original point was that we may have to rethink how we look at (listen to) our systems in light of the technology. My admittedly limited experience with the lenses suggests that such a rethinking may very well be in order. That's why I posted.

If you hear differently, no problem. I view this forum as largely a learning experience where we share observations, perceptions, etc....and we may sometimes disagree...but I would hope that out of the dialogue we wind up broadening our vistas maybe just a little. That's the point, I think, of communication. And if we can do it without seeming to bash the other person, so much the better.

No sweat. It's cool.

Mike: Possibly there was some digital Hi-Freq. glare that the room treatments had an effect on in CD mode that is not present in SACD mode. That would give validity to Jim's Statement, as the room tuning would not have an effect on something that is no longer present. Regards, HiFi Guy.

I thought of that too. If that was the case the room lense would have effected the SACD playback the same way, in other words it would be audible.

I'm outta this thread. It's becoming counter productive.

As an owner of a Linn turntable with 20 times more LPs than SACDs, I could imagine hearing LPs "stomping SACD in the Dirt", IF the SACD player was not tweaked to the max, as digital requires.

It would be hard for me to imagine this sort of vivid discrepancy comparing a good turntable with a TOP quality SACD player resting on BDR Cones/Shelves and Vibraplanes, damped with a little Rock from the top, treated to gourmet A/C by a King Cobra Powercord from a Power plant, with SACDs Illuminated by Auric.

Sure, all this could cost much more than a good turntable. But getting stomped in the dirt? Maybe if the special flavour Vinyl adds to the master tape, or that extra musical coherence at the minutae analog level that can't be captured even by DSD sampling, were particularly important to the listener.

But what about those guys with vinyl? They are listening to sources, that are sitting in that SET/horn era. All the recordings have been done in tube-analog(midrange) quality? Why we all love them and some consider as references in what we can hear?

I use a homebrew isolation platform with an innertube, jumbo DH cones, spiked rack, VPI "Magic" bricks as well as a high quality PC plugged into a API conditioner plugged into it's own dedicated power line that is shared by no other component or electrical device (to my box). I use Optrix. I have a Bedini Clearifier, I also have a Stoplight enhancer. The cables are Goertz Silver. Some of these tweaks made a difference and yes I agree 777ES requires TLC.

In the areas I mentioned above I stand by my feelings. I'm hoping to see a player come out with direct heated triodes or maybe just triodes on the output. Then I'll probably be further under this SACD spell. Till then, I will enjoy the Sony.

I didn't disparage a thing. You certainly did though.

Sorry, you haven't heard my horns or SETS. You also haven't heard my TT. Yet you feel free to make bullshit statements like I don't know "accuracy". I however have heard and own an SACD player.

So there! LOL.

Use live music as a reference instead of analog, digital and whatever. If the system sounds more like the real thing with a particular playback system then it is the one closest to the reference. SACD is fantastic, to me it still lacks refinement in the midrange and depth. I think better players are on the way, and they may "stomp" the vinyl in the dirt. So the wait continues..

Re: Re-thinking the system, posted on November 28, 2000 at 11:43:42
Anyone with any knowledge of electronics & the appropriate eguipment can measure the widely varying frequency response into different loudspeaker loads of SET amps. This is a technolagy that was "state of the art" in the 1930's. Since the very definition of "high fidelity" is that there be as little change in the output of a system as compared with the source, SET amplifiers do not meet that criterion. However, with certain horn speakers the SET amp covers up the deficiencies of the Horn speaker. If this sound is pleasing to you, thats fine, but if it is to be considered HiFi then we'll have to change the meaning of the word. As far is vinyl is concerned, I have a large record collection, mostly acquired in the 1960-1985 period that I still listen to & enjoy on my Linn Sondek TT. I didn't purchase a CD until 1993 & still find the sound of records more enjoyable to the sound of most CD's. However,SACD is a total different ballgame. It offers the best of vinyl & more & fullfills the best attempts yet at copying the master tape. These benefits are provable in both objective & subjective terms. However a accurate system with a flat response is crucial to the evaluation of any source, hence IMHO with horn speakers & SET amps you are not qualified to evaluate this format with a statement"vinyl blows SACD away". This would be misleading to other possible adopters of this format. If you are happy with your system, thats good, but if you are objective as well as subjective, you will have an open mind as to how this format sounds on a truly accurate system.

I am trying very hard to approach this new medium with a very experimental and open-minded bent. The backward comparisons with CD's and analogue are self-limiting. DSD does not sound like either, in my experience. We are all just learning.

I think there is a great deal more going on that those of us who have and will make the plunge are going to be learning together. It would be wonderful if this could be a forum for learning, as well as debate.

I may be moving onto some thin ice hear, but I wonder if we are not seeing some time alignment issues with SACD. When I first moved to the Jenna Labs products, I experienced something similar. My subjective experience was that high frequency information was less disconnected from its apparent source (the theorize sourced of some of the digital "hash.")

Perhaps this is why I am experiencing less of a need to control reflections in my room, and "opening" it up more by changing how it is tuned.

Highly subjective, but what I am experiencing.

Actually, the room coloration reference was a joke, referring to the multiple colors on the walls and ceiling of my listening room.

I don't think anyone was seriously suggesting that an SACD player will alter room accoustics, and in that you sort of missed the point. The point is that, at a rudimentary level, some of us are rethinking our room treatments in light of the subjective experience of listening to SACD.

As to hyperbole, well we all can accept a mea culpa on that!

Maybe for you and others that may be true - but to me room damping has little to do with equipment choice.

My analog front end sound great within the same room, using the same damping as my digital plus the 777 in sacd mode(borrowed) was also excellent, displaying great focus.

The same room!!!

Rick, my room damping was done to tame reflections of walls that potentially "smear" the image, including phasing errors of allowing reflected sound to "invade" the soundstage while helping to keep the sound in focus even during loud dynamic peaks.

My damping had nothing to do with source problems or inherited tonal problems of other equipment.

I should point out that my room was set up using analog and digital - and getting better analog equipment or digital equipment did not change the rooms nature!

I can only understand that by having terribly bright or boomy equipment would damping need be removed or added, but in that regard the room is still not at fault.

Re: Re-thinking the system, posted on November 28, 2000 at 12:37:46
Not to criticize anyone's particular likes & dislikes, I will only state that a system with an irregular response will impart its own quality on a recording. Sometimes this will be benifitial, & other times will be detrimental. All things considered, a system with low distortion, wide range smooth freq. resp. & that ability to recreate the depth in a recording is the only way to reproduce the intent of the artist & recording enginner accuratly. Horns do have fairly low distortion, partly becuse of their high efficiency. However the tonal coloration of horns negate, for me at least, any advantages they might have. They are also directional & give a limited "sweet spot". I used to sell Klipsch speakers & owned K-HORNS. After doing numerous comparisons with planer & cone speakers, side by side,With the K-HORNS it be came obious to me that the best chance of obtaining a truly unbiased presentation of the source lies with a well designed cone speaker. That is not to say that a good set of horns can't be spectacular sounding, but if you stick solely with a horn speaker you will be missing a lot of detail present in the music. Regards HiFi Guy.

My idea with SETs is to couple them to the appropriate speakers to maintain a flat linear response by using the proper drivers, impedence compensation networks and electronic crossovers. The horn also must not add any coloration. I find the round thick wooden tractrix profile horns have little to no low coloration, plus they don't through the waves all over the room like domes, cones, ribbons, and planars. I use TAD drivers, the compression drivers alone are $1650.00 each. The woofers are $685.00 each and the subwoofers in wich I use 8 of them are $450.00 each. The large wooden tractrix horns used with the "tweeters" cover a range from 300 cycles up without an additional crossover. They have an efficency over 115 db with one watt and the drivers are used in what is considered by some to be "the best" studio monitors ever made. The ability to unravel the smallest to the most complex recording accuretly is the TAD's Forte'.

I have owned Dunlavy's, Von Schweikerts, Infinity, Genesis, InnerSounds, Magnepans, Apogees, B&W, Dahlquists, Spica's, Soundlabs, ect.... as well as "high-end" amps to drive them with. None of them can match my horns and SETS as far as telling the TRVTH. These ain't your typical Madisound boxes, I can tell ya that. SACD sounds fantastic, but as I said before I think it can get better based on what I'm getting off of LP's.

Mike: How did you measure the response & IM distortion? Did you use a spectrum analyser? I have never felt the need to spend the countless $$$ that you have to obtain accurate Hi Fidelity reproduction in my home. I have my room tuned to +/- 3 db after much work & measurement. This response is fairly uniform over a 60 degree window, measured with a spectrum analyzer. I have never heard a horn loaded design that didn't suffer from coloration, however that is not to say their isn't one. I believe their are far less expensive ways of obtaining truly pleasing accurate sound reproduction.

Re: Re-thinking the system, posted on November 28, 2000 at 13:39:30
Mike, you didn't answer my question as to how you arrived at the various impedance, frequency & crossover values that you used to obtain accurate response in your room & equipment used to measure the results. I relied on established companies that have the needed facilities to achieve the result that I was looking for. I believe that anyone doing the same will save alot of grief & $$$. Regards,HiFi Guy.

I understand your points. My point is that I have been able to open my room up more with SACD. Frankly, a lot of the tuning I have done has been in response to digital, not my analogue sources.

This is ONLY audio!!!!

No need to justify one's preference in choosing different technology.

I am not a SET fan, although I am aware and respect the fact that many reputable audiophiles love it. I also have heard and liked SET, tube amps and SS amps. I prefer SS not because it is better, but because it is my preference to the music I like!

I also respect the fact that Mike owns both units and his decision making process is based on first-hand experience. Why would you Mr 'HiFI guy' speculate that his findings are only based on his SET preference. Did you invade his home and make that decision on fact - or just empty speculation based on the theory of measured performance.

Anybody with a subjective thought would realize that maybe - Just maybe - Mike was correct! No No No - Instead because of SACD rhetoric - he (or his system) must be doing something wrong!

Why?

To this day I have heard SACD advocates claims that speakers, lack of break-in, rooms, and different amp technologies are all major limitations of sacd sound, esp compared to cd and analog.

Mike and I claimed SACD sounds excellent, yet thats not good enough!
What Next?

Of course live music is MUSIC, but we are dealing here with "music reproduction." If I say that the best recordings are from era of tube-horn I think about the reality. I admire the work of people from that era...They just did the best even with a limited "technology" available. Which translate to "hand work". Digital will always be artificial.

There is always that certain magic that only materialises from DHT tubes and Vinyl, that would be forever alien to SACD and solid state, no matter how truthful or accurate they may profess to be!

In an AES workshop, David Moulton shot theoretical (psychoacoustical) holes in the whole idea of early reflection absorbtion in small rooms including studios. He had a demo in his hotel room that was fascinating, no room treatment at all and a huge soundstage using speakers having a flat directional response. They had even taken down the curtains!

Great food for thought...

 

Re: Re-thinking the system, posted on December 9, 2000 at 20:25:52

Deviating from the discussion of SACD's and horns (I have heard them and built them, but it's been some time ago), has anyone combined a SACD with a good planar speaker, and if so, what were the results? - I have the MG-3.6's, which have a ribbon tweeter that may actually reproduce some of the SACD's ultrasonic noise. Though I love the Maggies' smooth, extended, transparent response, I am wondering how they will work with an SACD player. - Any Maggie/SACD owners out there?
