What do you see as the downside of tubes?


I have decided on getting a tube amp and it will be the integrated Mastersound 300B driving a pair of Living Voice Avatars, so at least that decision has been taken.

My main question is what you see as downsides of having a tube amp. As I've decided on getting an integrated tube it's really about what the downsides are I might want to know about beforehand.

The ones I'm aware are the following.

-The tubes need to be replaced and in the case of a 300B this will be somewhat costly.

-Bias is another issue but I'm not sure how big an issue. Do you plug in your meter every so often or just when you roll tubes or replace a dead one? The meter as such isn't gonna be a big issue as I don't think it's that expensive.

-Heat won't be a big issue as we have no kids nor a nosy dog that could get burned. Hope my electricity bill isn't gonna go through the roof, but then again, I can't quite imagine that.

I'd appreciate if you could add whatever your experiences are regarding this question are as I'd like to know more before I buy it.

Thanks

Jayfox, Re: "In defense of Dave b". I too understand what he means but more importantly I understand why he arrives at his conclusions. That I think his reasoning is flawed, and certainly not in accord with mine (or yours) but what pleases his ears is all that counts in his house. However, anyone who considers his observation as any form of 'truth' certainly risks great disappointment.

BTW Jafox I agree with your views, especially those suggesting that signal decay is more often than not a signal truncated prematurely by most SS (and some tubed stuff as well) which makes their sound initially sound more "transparent", "detailed", etc, when in fact it is really inaccurate and creates a sterile, fatiguing sound, even though the frequency response is relatively flat. But some folks like this sound. I'm sure they would find 'my sound' thick, bloated, dense, slow, etc.

Dave b, A question - regarding your analogy involving the sound of music in a jazz club as reproduced by your system. Are you referring to performances you actually attended and that you have heard unamplfied performances, or that you have actually heard the events live that you are now listening to in a recorded form and that you are confident that you are in fact hearing something that occurred in the performance, not in the mixing booth (etc)? FWIW, I always find the assertion that someone finds any recording played over any equipment ever sounds like a live performance. It typically suggests to me that the person doesn't know the clues to listen to or doesn't get out much.

For example, consider that most live jazz club performances are not played with out amplification for each instrument and their sound is blended in with the sound of the acoustic (room) that may be overly resonant or damped, or that the amplyfing equipment itself, or speaker placement, produce an overly dense source, isn't it then possible that a SS system which truncates the signal length only makes the recording/your system sound move like a real live and unamplified one? Just a thought...........I don't understand how you can sort out all of these varibles. I always think that the best we can hope for is that we own the equipment envisioned by the recording engineer and that his efforts to make it sound 'live' are successful.

Hey Bill, Keep stiring the pot! But, why not share with us your underlying reasons for arriving at and making your terse observations. That way we could see some meaningful mud slinging! :-)
Tvad, A good observation. It was this exact statement that got my 'interest' going and was the fundamental reason I posted. I suspect that if I heard his 'optomized' soundstage I would consider it as unrelated to the sound of a live event as the lack of reality that he seems to think would be introduced by the use of 'tubes'.

None of it sounds real, amplified in the venue or not. SS or tubes. And, IMHO, it is not even close, so why not just pick the sound that you prefer, tell youself that it is as close to your recall of real as you can get, and be happy.

He seems to have overlooked the fact that the OP didn't ask for a discussion on the benefits of SS v Tubes, a decision that had already been made. Seen in that frame, which was my frame of reference, I couldn't understand why he would bless the thread with his observations about his views of the strengths of SS and the 'apparently' universal weakness of tubes.

Oh well, time for me to shut up as well. :-)
Dav65mus, Be careful what you wish for, especially if you like what you presently are using. The road to audio hell is paved by folks trying to make a meaningful positive change to get only a small, or any, meaningful improvement. Different perhaps, degredation often. Buckle-up before you take this road! :-)
