In Reply to: RE: I'm guessing posted by GEO on January 02, 2015 at 18:58:49
I'm afraid it wouldn't. While I was gone from this forum, it degenerated into schematic-sharing (schematics which I would never build anything out of-- for many technical reasons, the main ones being that they DO NOT perform well enough, and are not reliable enough).
It sported the trading/sharing of old, and almost totally forum-approved worn-out electronic/audio theory-- and produced nothing of unusually high quality, yet still had plenty of the usual backbiting anyhow.
Actual audio performance that sounds most like a live performance remains the standard, but it was largely ignored here except when someone questioned the status-quo long enough to actually think logically, and then act without bowing to and paying homage to professionally herd-trained mentalists that produce strictly ordinary results.
All of that is quite normal in any public forum, it's a part of human nature. The fact that it occurs here should not be considered unusual.
It is when we advance BEYOND normal negative human behavior, become pro-active and look for REAL excellence that we are finally able to become logical, forget what is inferior that we already know, and advance beyond that and start independently searching for the Best.
The Best IS attainable, it is not usually done on forums and is almost never approved of there.

I am sick of this....you are a condesending arrogant know it all.... no one is a smart as you and your side kick...no one knows what sounds good, how to build an amp and so many other things that spew from your big mouth....all you post is pontificated BS... can't back anything up you say with any sort of technical knowledge....stop continuing insulting people or just go away....
There's a better world out there!
Search for it.

your world of self delusion is the best... you are so full of yourself
Why iss Dennis continually allowed product placement bandwidth here????
Listening to recorded music is generally a form of self-delusion - a very enjoyable one. Some of what we do to "enjoy life" occurs by accident, but it is, nevertheless, real. The explanation is sometimes debatable.
But WTF!
Observe, before you think. Think before you open your yap. Act on the basis of experience.
Opps I see the the Medwins have been crying to the moderators again.
You got it awsjr. But DF and JM are protected here and we are not, so don't be surprised if these posts get erased.
Hi Ray,
Incorrect !! WHAT in the world makes you thing JM and DF are protected here ?
The posts that got erased are ones not fit for proper decorum, like GEO's pictures of Flies on Feces, or Pigs with make-up.
They didn't kick GEO off the Forum, or issue him a warning I surmise, they JUST deleted his posts that were crass and in poor taste.
I say the Bored has been very fair. If its out of line, and complaints are brought to their attention, they will act in a fair and legitimate way to clean up trash.

Dennis, I agree with a lot of what you say about endless re-workings of 300B/2a3/45 amps with high mu drivers. It's an old formula, but there again it works, and you've used basically the same idea but with a number of novel twists to it. So the old and the new together.We have a lot of evolutionary circuits and they steadily get better, so that's not a bad thing. But we've also had some revolutionary ideas that haven't been cast out - on the contrary they've been well received and incorporated into further experiments. One such was filament bias which Thomas Mayer popularised. This has now been used in many good 26 preamp designs. I took it a stage further and used it in the output stage of a PSE 4P1L amp since the 4P1L is one of the absolute best candidates for filament bias. Works like a charm. That was well received and there have been some builds of it with good results. I didn't get any animosity or lack of acceptance.
Bottom line - there are a lot of formidable intellects on this forum. This is highly technical work, and in terms of personalities you would expect them to be fairly radical thinkers - we're using tubes here not solid state. Portraying the forum as a load of fuddy duddies immune to new ideas is just not the case at all, in fact it's far from it. I'm in awe of a lot of the forum members, and a few have been my gurus through my building experiments.
And in any case, circuits survive on their merits which is good scientific sense. One of the problems you're probably referring to is that there may be a period of months or years before newer ideas circulate and get incorporated into builds, so there's still a lot of the old around. But I bet if you looked at the workshops of forum members and saw what is actually being built as we speak there would be some nice fresh ideas happening which we'll get to hear of later.
So when you say "Actual audio performance that sounds most like a live performance remains the standard, but it was largely ignored here except when someone questioned the status-quo long enough to actually think logically, and then act without bowing to and paying homage to professionally herd-trained mentalists that produce strictly ordinary results" I completely agree with the ideal of radical thinking from first principles and of reproducing the actual sounds of acoustic instruments. All good. But I wouldn't call a number of members here (many of whom I know personally or communicate with) "herd trained mentalists". That's not right and it's not fair.

Thanks, Andy.I did go a bit over the top. MY bad....
No excuses from me. Call it exhaustion if you please. I just get a lot of BS. The other day a guy got into me for talking about using G.E. Silicone2 in many chassis. He must have assumed that I never made that many amps. That was jumping to conclusions-- I also modified a lot of them. Now, where do you mount that new, extra component?????? And how.......
In building and servicing movie theatres, I ran across all sorts of audiophile amps, and most of the commercial ones. Many of you know of those.
Well, my clients wanted better sound in their theatres and were willing to pay to get it. That allowed me to use any amps I wanted, or modify or build them.
Needless to say, if any of those amps went down on the job, I got called. It might be 750 miles from here, or more. That extra trip would negate anything I might have earned on the first trip-- those amps had to run for years without any servicing except for tubes every 3 years or so.
Now, let's see-- how many tube amps can do that? Maybe ONE brand, and only two models of that? It truly is that bad-- and it always was. Even the often revered W.E. Model 91 had reliability problems and sounded really bad.
It sounded VERY mushy and narrow-banded, it sounded like a cheap Clock-Radio. I hated them. Every time I saw one, I told the guy to get me a pair of McIntosh MC-60's, and let me redesign them, which, when finished--really performed. It was that, or let me put in good Solid-State amps.
For my own personal stuff, I tried S.E. amps because I knew they COULD BE MADE to work. At the time, none did, and I had tried them all, several from builders that are revered here almost every day. I was FORCED to design my own S.E. by the fact that the others didn't get with the music--or the programs-- in any meaningful way.
So, I fixed that problem also. The only problem I have with some people here-- and they are very few-- is that they just keep re-hashing all those loser-amps and their old technologies-- that never work well enough to convince someone that he is actually at a live performance-- which is what a movie theatre is supposed to do-- and what home audio SHOULD do!
And their reliability-- OH, MY! While being OK for at-home persons who can keep them serviced, it isn't remotely close to what one COULD have.
Some people are still playing with "adjustments" pots in amplifiers. WHY? You don't need adjustments-- you just need good designs.
And some people are still playing with Mercury tubes and rectifiers which slowly lose the Mercury through their glass envelopes. Well, the last time I looked, Mercury was the #1 Health-Wrecker in the USA. Mercury is THE most toxic element, according to numerous on-line health experts.
Some people don't believe me, of course, and that is their right, but why did I keep finding brand-new Mercury-vapor tubes in movie theatre's NOS vacuum tube stocks, which had so little Mercury left in them that they wouldn't operate?
I soon found out why! It was that super-thin grey scum that was on everything in the projection room-- objects in there-- in many, many old theatres felt a little "slick", and had duller colors than the same objects found elsewhere.. It was Mercury scum. People were even getting it on their hands while operating the projection room!
Andy, that's always been the problem with idealists like me-- we're aware of what COULD BE, and that puts us at odds with WHAT IS.
WHAT IS is always defended against what COULD BE.
I may be one of the few who brought the better COULD BE into WHAT IS... I actually did it.
I don't want any credit for it, and I don't make my living out of electronics in any case. I make a living doing construction work and building homes, used to drill oil wells, and ran resting labs at uranium mines. I once owned several movie theatres, and I did what it takes to transport an audience to the scenes audibly. It was fun, and it could work for others who love music like I do.

I know you mentioned sharing schematics so this should really belong in the DIY forum....
Building an old schematic/design is all a part of the learning experience. Most of us appreciate input from you, Jeff and many others that contribute to this forum. But, it's very arrogant to think a design is the "end all be all". Not everyone has the same tastes and are not always satisfied with 105db or less. Personally I'm maturing to these tastes but in the past liked to crank it up every once in a while to blow the cobwebs out. In the future (when I'm not so damn busy working) I will build an amp using your "modern power supply", I will not express an opinion until I HEAR IT with my own ears.
Let's change this forum in 2015 and have some constructive discussions.
Happy new year!
I might just casually mention something about large-scale dynamics, blowing the cobwebs out, etc., and about keeping musical instruments separated in time-domain while complex, powerful music is playing loudly.
Loud is GREAT-- if it's CLEAN.
Now, that's just what I like.
Now, how do you suppose I got that?
---Dennis---
This is what has been lost is all of this arguing. Little of it has to do with what the "modern power supply" sounds like. Its the made up science passed off as a documented truth. If Dennis and Jeff said, "we don't care about measurements and proper engineering, we just focus on the sound we like"...these threads would not be so long. Its the holier than thou based on made up stuff. They can say "we like a noisy power supply" and leave the engineering to others. I have yet to read someone say, they don't like the sound of Jeff or Dennis' amps. I know a guy that has Dennis amps. He loves it and he has had over 50 amps, including two or three I sold him. He does not care why they sound the way they do. He just likes them but he is not here try to pass off faulty knowledge as some truth.
I think that the flashpoint for the ongoing arguments here are largely to do with "made up science passed off as a documented truth." I'll add to that "passed off as absolute truth, for all people all the time" and the off-topic responses to questions.The ongoing behaviour - the thinly-veiled baiting, personal insults, off-topic jibes and apparent animosity - goes well beyond this. I think we should be well past blaming others for their actions while ignoring at our own part in this. I'm asking those involved where they believe their power lies: do they have an internal or external locus of control - do those involved believe they are responsible for their own actions? What are they trying to achieve and do their actions support their desired outcomes? Does their behaviour reflect well on their profession and would it be applauded by fellow members of their professional/member bodies?
There are a lot of people with much to contribute here, obviously. It is a disappointment that apparent professionals and intelligent people cannot conduct themselves in a manner that promotes constructive outcomes. Moreover, the moderators are failing to do what is required to this end.
It is starting to look like a lost cause.

I'm saying this to you with the utmost respect-- we're arguing over engineering, not building to taste.I NEVER build to ANY taste, I build to exactly replicate all the qualities of an input signal.
I look at this as a dynamic, moving, changing set of elements, not as static, non-moving targets that can easily be measured.
The object is to keep hitting moving targets dead-center as they are moving and mixing with each other. How do we keep instruments that are buried in the mix-- both distinct, powerful, and standing out-- yet not let anything dominate-- how can we follow ALL of the studio mix as it was laid down?
We're arguing how to engineer that, not how to build to a certain taste.

The more you post the more idiotic the message. Please spare us. Those that want to follow you and Dennis can easily do so in a sub forum. You don't see the OTL folks here stirring up the pot.
I love you guys !!!!! Suffered some losses this past year and after having not visited this site for a while, it's good to read I guess that the madness of the asylum still rules. GEO, you telling Dennis to beat it is the best laugh I've had in months . Thank You for the laugh !! I know NOTHING about tech stuff. Nothing ! But Percy Heath once told me in private that no matter what anybody tells you " the ears don't lie". And true enough we all "hear" stuff differently, and I have most respect for GEO and Tube Wrangler. And perhaps he rants, and a lot of it may be hot air but, and this is a big but for me..... Tube Wrangler's amp is the" best", un-disputed best freaking amp I have EVER heard. Period , end of story. So when I read the stuff he says and how much it pisses folks off,it just might be snake oil....... but for me, he knows something that I was chasing for years. I could not put my finger on it until I heard his amp. For me it's the truth. So what he says does not bother me in the least bit. Damn this amp brings joy. Let him be, for there has to be "something" in what he says for him to build this amp. With a pair of AVVT 2A3 mesh plates ???? DAMN
"And true enough we all "hear" stuff differently"
What does this even mean?
While we all have slight differences in frequency response etc, nobody I have ever met would mistake a clarinet for a lawnmower.
Nobody says "I bet this band would sound way better with a lawnmower"
"Tube Wrangler's amp is the" best", un-disputed best freaking amp I have EVER heard."
So we can surmise you have one of GEO's amplifiers and prefer the sound of the amp built by tube strangler?
Drlomu implied you have owned upwards of 60 SET amplifiers, would it be fair to say you might have eccentric tastes?
The OP has heard a "serious stereo" and prefers the Audio Note.
I find this a more trustworthy, then say someone who may very well have been summoned to this thread for defensive measures.
Why does everyone within this marketing circle SPORADICALLY apply CAPITAL letters in their grandiloquent RESPONSES?
Cheers
One more thing.... there is another amplifier I call "The Truth". It's built by another very special builder. It's called a 10-Square. The guy who built it does not post much I guess, but assuming you are a lover, if you ever get the chance, taste either one of these SETS. They continue to bring such joy to my spirit. I'm not one to argue but I'm thankful for the guys who lead me to both of these amps. By periodically telling folks about this experience, it's my way of perhaps leading someone to something very special, who like me chased amps for years.
You have missed the entire point of the threads. No one is saying his amps don't sound good. It is the made us science that he is passing off as facts and the technical advice that is just not right. Jeff and Dennis like the way their amps are tuned and many people agree. Its like JHogan. Noboby would build amps the way John did but he never came on the board and said everyone else amp is wrong and his is right. These arguments have little to do with the sound of his amps if you have been following the threads. They are so specific in their power supply builds and their methods, that he should sponsor a forum like the OTL instead of hijacking the SET forum whenever someone posts a question.Your buddies said the their are problems with the power supply in your 10 squared which is a stacked supply, I believe. Larry does not mind them but that is reason why Dennis and Jeff should just sponsor a forum like Ralph does from Atma-Sphere. It would clean up the sight. Nobody would go there to visit other than those seeking to drink from their water cooler. I don't know why they are so opposed to it?
Edits: 01/06/15
Let's clear this up once and for all:
(1) "made up Science". Ridiculous. Any good engineer can figure it out-- ALL of it-- easily.
(2) "Passing off as facts". Sorry again! Facts ARE facts. I just pay close attention to FACTS, rather than copy irrelevant "facts" from wrong, but accepted sources.
(3) "Like the way their amps are tuned". Sorry, but these amps ARE NOT tuned. They ARE neutral.
(4) "opposed to it"-- a separate forum. What is the price? Maybe one could afford it, who knows?
(5) "drink from their water cooler". WHAT does this have to do with accurately reproducing music? I know that most forum members care more about an amplifier's musical accuracy than a posted-POLITICAL position. I KNOW they do! Otherwise, why should I post at all?
"The most important skill for Science is noticing the unexpected".
---Dennis---
Whatever you say...one would argue that the most important tenant of scientific inquiry is the notion of the "theory" standing up to peer review.

Nope , I don't have a dog in this fight. Audio Note ?? Nope sorry, not even close. As to GEO, we have a "history". I have purchased many of his amps on Audiogone.
Eccentric taste ? Maybe that all depends. I come from a family of musicians. I "know" what live music sounds like. I grew up in a home where I knew Miles, Monk and Trane as well as my ABC's. So if natural sounding uncompressed music makes my taste "eccentric or suspect you then oh well. Duke Ellington once said there are only TWO kinds of music Good and Bad. As far as Dennis goes I bought his amp on a dare, cause I to grew weary of all his bloviating. Then I listened...... I heard the "truth". End of story. I no longer buy gear. I just listen to music. Life is good. Be kind and have a wonderful year. I'm going to go back to listening to this eccentric cat at the moment. Eric Dolphy
Jeff and Dennis claim to have broken some bounds of known science. Don't you think it is noteworthy to document something so profound as the theory of relativity? This is not about what the amps may or may not sound like but rather, made up stuff to try to explain it. It may do them and everyone else some good to document and subject their work to peer review which is typical in the scientific community but for some reason, engineering an amplifier is beyond science but engineering a TV is not? Its silly. They should sponsor their own sub forum here (like atmosphere does in the OTL forum) so that their devotees and those that want to adopt their principles can follow them. Do you seen anyone over in the digital section bashing digital because they like analog?
Edits: 01/06/15
GEO,Wait a minute, SHOW me please where there is an Atmosphere Forum ?
I don't see one. If you see "all theses posts" by Ralph, might they be in the OTL FORUM, because Ralph builds OTLs ??
Dennis and I are interested in SETs, so... why not post in the SET ASYLUM ??
Are you making-up things like an "Atmosphere Forum" up in your mind, dear Sir? Good imagination GEO.
BTW, that RCA - Apple chart I posted only went to 2012 on Apple's stock price. Lets update !! In Oct-Nov 2014 Apple stock MADE the "right-side" of the head and shoulders top, like you talked about!! It went to an "all time" high in Oct-Nov 2014, JUST LIKE RCA did in the 1929, just before RCA crashed. Wow.
Never confuse a company like RCA or Apple "remaining viable" as you said, with losing 90% of your invested money QUICKLY - in a stock's decline. The company may remain viable, but in your lifetime, you usually don't get a second chance. You don't live long enough. 2009-2014 WAS "everyone's" extra-ordinary second chance to recoup, the party is OVER.
GEO, in December 2014 Apple stock feebly did a BEAUTIFUL non-confirmation, while the general market made new highs, and AAPL HAS "rolled over". Apple is best now as a short sale. I shorted GE instead, last Wednesday, and I got it done within 10 minutes of the high for the day.
You GEO, are likely on the wrong side of the Market!
Its going to be absolutely HUGE - this drop. A little more market action and I will know for sure, if its NOW or later. But, proactively by last Wednesday, I personally went "ALL IN" on the short side, 100%. So far, so good !! We should be seeing DOW 7,000 quicker.... than most everyone would suppose !!
Send me your private email address and we can discuss this stuff off Forum!!

Once there was Tube Asylum, then there was SET Asylum, then there was DIY Asylum, then there was OTL asylum (which is sponsored in part by Atma-Sphere). I am just suggesting a modern power supply, 3D wiring, or modern construction technique Asylum. I don't understand the resistance. Seems to me that like minds would find that space helpful.

You write :
"Once there was Tube Asylum, then there was SET Asylum, then there was DIY Asylum, then there was OTL asylum"
That is correct GEO, and these Forums still exist today.
But there is NO 'Atmosphere Forum ' - just Atmosphere as a PAID ADVERTISER to AA. My goodness, they have maybe ten retail dealers, are a full time operation, and Ralph was doing this in the 1980s in Minneapolis when I knew and worked with Bob Fulton.
Dennis has NO dealers, we do not count on audio to support ourselves, and I have "volunteered" to help him run a RMAF show here and there, because I have heard his handy craft, think it is extraordinary, and support him as an amateur any way I can.
What he and I are trying to bring to this Forum, is a sense of how to build a better audio amp, starting with a power supply approach that works like gangbusters. No need to scientifically explain it, I certainly can't, but I KNOW what I've heard in amps and speaker listening all of my years, so I KNOW when its right on playback.
There is no marketing involved, that is a smoke screen, a ruse.
BEST of all, Dennis latest amps are WAY better than anything else he has built, so, we can back-up, via listening, and prove the superiority to anyone who is interested. It you wanna dumb-down the audio arts, maybe YOU need to find a different Forum to post on, or a sub forum??
Which leads me to ask an question. What is your position in the audio industry? THAT would be nice to have you fully explain. If lakerfan is buying three SET amps from you, what are your interests here in going after Dennis and I ? Answer that fully for all of us, sir.
Jeff Medwin
He bought my Don Allen Amp, my Larry Moore 2A3 and my Burgess 45 / 183. He is a good guy and I have known him for a long time. As for the rest of your post, whatever you say Jeff.

I agree. I'm no "fan". I dont read their "stuff". You perhaps know BS when you read it. I simply don't read his stuff anymore. Have not for a while . Not meaning to be insensitive to your exasperation, I simply don't read it. What I found humerous was the fact that I have not really been keeping up with the Forum like I used to, but the moment I decided to have a peek.......... Dennis is still at it. Hilarious !
Happy new year. I posted some nice jazz cds I picked up in 2014. If you are looking for some fresh music, take a look. I still have my 801A :)
I believe my 10 square uses an 801 as well. Have not put them in yet.
"Actual audio performance that sounds most like a live performance remains the standard..."
With the qualifier that i am not a musician - like Andy Evans - who knows what instruments really sound like, my position is that SET appeals to the personal emotions aroused from memories of listening to certain live performances. SET sucks you into the performance; while the most "truthful" systems just lay it out in front of you to dissect and observe. (This is Bob Neill's distinction, not mine, but I agree 100%).
Our ears are antennas; the brain reorganizes the signal to match what our experience holds most dear.
I remember sitting down with you Dennis, alone, in your room at RMAF long ago, listening to a Native American woman soloist and my memory of our conversation is that what you (and I) heard was the beauty of her voice - "the rapture", not the truthfulness of a live performance.
We are an imaginative group...
So much for projecting my own beliefs on others.
Observe, before you think. Think before you open your yap. Act on the basis of experience.
What you heard was what the woman sounded like in the studio.
There were no euphonics present, just the track being played accurately.
That's not to any taste, it's what she actually did in the studio.
If you'd like ONE component that gets this totally right, then get Berkeley Audio Design's new "reference" DAC.
