But I caution you about your psuedo-science and buzzword talk around here.
On Madisound/DIY speaker sites they just laughed you off, over here they will crush you if you try to vanguard BS them.
Enjoy your search, but don't go into it with preconcieved notions that you have either heard of or thought up. Some tube based units sound wonderful, some sound bad, same can be said of solid state, just with many inexpensive tubes the speaker match is more critical than with inexpensive solid state.
And take it easy with the BW generator or this "Eddy current" will short out.
I wasn't laughed off. They all asked me to leave & I obliged. Hopefully w/o me around they'll mature.
::p:::No one asked you to leave the forum at MAD publicly, as far as I know, yes they did bully you in anger after monthes of battles-your retreat was your choice. The irritation came from verbose misinformation on your behalf, confusing the newbies. Ed is correct-read the Madisound archives for more info. I have never perceived you as a flame bait, but apparently coming to a tube site and questioning the foundation of this amplification medium is in poor taste. I would have kept my keyboard quiet, but I do not feel the MAD people were childish in the least.Yes, there are some lousy tube amps,yes, there are some lousy SS amps, and yes there are excellant examples of both.Yes, a nice one will blow away that Adcom you have, no many tube amps will not properly drive ESL's but some will. This is a moderated forum I have recently discovered, since I don't want to be kicked off I will refrain from any further posts in this thread-you of course can have the last word::p:::

We all know how vital that is. Anything with a slew rate of <100V/usec. must be melted down and sold as scrap metal!
BWAAAAAHAHAHAHAHAHAHAHAHAHAHA!!!

Sorry... That message number is not valid.
Do NOT turn this into an AVA/Legacy advertising site.Keep your mindless repitition in AR they will NOT be tolerated here.This site is moderated. You will get no more warnings.
Jack
It's like a tweeter w/ a setting time > 1/2 ms. Completely worthless!
Ò¿Ò
Maybe Mart should buy something with 811 triodes in it.Designed for amateur radio use it has a slew rate in excess of 1200V/usec.The Altec 1570B uses one pair to put out 170 watts.The thoriated tungsten filaments look pretty cool in the dark too.Not bad for a tube you can buy NOS for $12.
Do you read about your equipement or do you listen to it?

what's the best configuration & why.
If I'm forced to order an amp deafly, I want to nail down some irrepressible facts. I'm continually learning the hard way that my tastes do not fit the constituative mold, as the items I desire are quickly deemed obsolete for more popular inadequate designs. But they are usually measurably different by Physical design. Thus, if I find a truly superior design, IMHO, time must be of the essence. Because its total shelf life will be measured in months.
Why do they build hybrids whose majority consist of a tube in & SS out. Apparently, to reduce (interconnects & speaker) cable dependancy as well as (Z & back EMF) driver issues.
What still bugs me is matching a current-source & a voltage-source in the same circuit. Thoughts of tank-circuits w/PLLs in the biasing & low-Z signal bleeding from both devices sounds quite non-linear. But, I'm sure this is very design sensitive.

the best way is to listen-intellectualizing your stereo doesn't work, unless you dont rally care about the music, or you think it all sounds the same. At some point, you will have to actually listen to it-published specs wont tell you how something sounds.

If you cannot borrow one, buy one on a 30 day trial period. Thats standard.

PS, since you're not a tube fan, why post on the tube page?
1) The mear size of a the tube's following, makes me believe that I've been missing something. And like you, I don't want to miss anything that might improve the sound that I'm hearing. Everyone here indicates that all tubes are different, which sounds like a mixed bag. On one hand, there just might be a tube fixture that doesn't require a mortition. And on the other is a sinking feeling that there is something inherently wrong with the device that may vary that much for almost no reason (or, @ least it seems nobody bothered to find out).
2) I like tubes in drivers that aren't "dynamic". It has been my limited experience, that the more the driver excurts the duller the sound. The tube seems to compress & soft-clip the sound to give it a very artificial plastic sound. But on the bright side, tubes seem to preclude most dynamic problems (echos from horns, ringing in metal domes, tweeter diffration, conical breakup, port booming, and XO IMD).
It's not that I'm banging a drum against "tube usage". It's more that I'm on a quest for clarity for both amps have pros & cons. I'm looking for a better blend than that's touted. But to do this I've got to learn. So, I sit @ the feet of the tubers, and learn their POV. And in this way I may find the "pot o' gold". Anyway learning is great fun, even if it's humbling @ times. What do you know, a double blessing.
For your deft use of the English language and for consistently butchering the technical aspects of audio, I dub thee the "Norm Crosby" of audio. Congratulations!
Cheers.

Yes. You have been missing something if haven't heard a properly setup tube amp.

Not sure what you're getting at here. Think you could rephrase a little?
> > The tube seems to compress & soft-clip the sound to give it a very artificial plastic sound. < <
From my listening, the musical intruments sounded more real than they did on SS. High frequencies do contribute to detail, but the quality of the midrange will will have a greater affect on the musical presenttion. In general, tubes reproduce midrange better than SS. Have you gone to the web site that I posted under Scott Woebcke's post? There is some theory there as to why tubes have a great sounding midrange.

Are you talking about hybrid amps? Kinda confusing statement here.
> > I may find the "pot o' gold" < <
You are just going to have to experiment yourself to see what is right for your tastes. You can't quantify and then experiment. You have to perform the experiment first and then quantify your results.
Have fun,

He has no interest in buying or even listsning to decent tubed gear. I don't personally care if he listens to tubes or not(and he wont) He's just jerking our chains. He apparently has been asked to leave other sites. If he continues to play games, he'll get deleted. No more games, no more warnings.
Jack
Maybe I'm too forgiving. If things do get worse, I'm sure you won't hesitate to bring the hammer down hard.
Have fun,
Tom S.
