Tube Amplifier Sound Characteristics

@kw6 I agree the integrated are really good. I remember last year I was at a audio dealer showroom and he said he was putting on an integrated and I snickered and then heard it and was amazed how far they have come. I personally think it is the wave of the future as the demographics and industry have changed.

But as we all know sometimes when we insert different equipment into our systems, the sound changes. I have to admit I don't know what "true neutral" is. How would I know?

@jimbones The only way I know isn't easy. Get some great microphones and record an ensemble of some kind- and then have it on whatever media you prefer. That way you know how it should sound because you were there when the recording was made.


Otherwise you play natural recordings that have good merit and listen for the things that they are known for. As those merits improve (and lessor recordings don't get worse) when you change a component, you'll know you are on the right path or pretty close.

Man, I love when @atmasphere joins a discussion! I really appreciate learning the “behind the scenes” details from someone who truly KNOWS! I don’t have much to contribute in terms of what one hears as a result of electronics design, but I can say this: the only way to know what a component sounds like, is to insert it into one’s own system and listen. That seems obvious, and it is stated here often, but its importance is still undervalued. “You can’t judge a book by it’s cover” (or a component by it’s circuit), is very appropriate in audio. I’ve been surprised many times by how something sounded, as a result of my expectations suggesting one thing, but then reality showing me those expectations were wrong. And that goes both ways: expecting great, but hearing mediocre.. and expecting mediocre, but hearing great

Well done, Ralph! Cheers,

as was said, if someone made a graph of sonic attributes for any amp, SS or glass, the author would regularly be challenged.

at least to my ears, lately it seems more and more tube power amps tend to sound similar to Ss amps.

When picking any amp it seems to me one should enjoy what it provides in its unadulterated form, first.

I want a tube power train usually as most often the outcome is more pleasing than what one routinely gets from pure SS amps, AND with Tube power one can address their audionervosa from time to time by rolling the dice and spending far more money and replacing what the designer felt were optimun tube choices at the onset of their construct.

always I want a tube amp to sound unlike an SS amp… mostly. as the result of distortion? of course not. ultrra euphonic? nope. not that either.

what I find preferable with tube power done right (IMHO) is a fuller, more dimensional more organic presentation which enlists leading edge definition and does not ignore the natural decay of tones. one where imaging is as prominent though no more so than the balance of its delivery of the entire bandwidth.

… and I like it to be a little bit wet sounding.

regardless one’s preffs this past time is about personal involvement and enjoying the music being rendered.
if the end result floats your boat, butters your bvread then all other reputed soothsayers be damned. you are the one who has to live with your rig… not them.

as for tube poewr amps that really grabbed me, they were not power houses per se. often rated at less than 60 watts per ch max, and usually less.

as for a subgjectivve account of the OP’s short list, I’fve only heard the VTL and ASL. both were in completely different set ups and different rooms. my only take away was the ASL amp array yielded a more prominent mid range whose protrayal came across as more solidly done.

there are far too many variables in compariing amp attributes let alone the subjective assignements each poster will attach to their comments to develop a valid consensus.
