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

Krauti, GM as well as some other major car manufacturers are very capable of building some of the worlds best vehicles but it is a terrible shame that top management failed to make the transition from gasoline vehicles to greener transportation. They had plenty of time to contemplate this years ago. Global warmer is a serious threat and if we continue to on the path were on, no one will be employed. Will be too busy trying to survive.

Anyway there is a downside to everything, both solid state and tubes, just pick your poison.
Kruati, I bet next time you'll phrase your question differently. ;-)

98% of this thread is complete nonsense, but Phd's last post really took things down the crapper.
This thread has outlived it's usefulness and as Dan_ed points out, it's definitely gone "down the crapper" with Phd's asinine remarks. Maybe we should all scrap our inefficient gear and go with class D amps to save the planet. NOT!
When did this forum become so mean spirited? I can't rememeber when we've seen so many personal attacks in one thread. It would nice if we could return to succintly responding to queries and approriate discussions without the personal afronts. Perhaps those that feel the need to lower the standards of this type of dialogue should frequent that other site?
Unsound, perhaps you don't see that the majority of the posts on this thread are answering the question "what do I not like about tubes". After reading the original post by Krauti, the question being asked is really "if I own tubes, what do I need to know".

And the bullshit political rhetoric as well! I don't care which moron or which moronic cause anyone supports in politics. It just doesn't belong here.
