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

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".

It would nice if we could return to succintly responding to queries and approriate discussions without the personal afronts.

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.
Dan ed, my comments in regards to GM were directly related to Krauti's last post that he was hopeful that he would still be employed by GM because of their recent filing for bankruptcy. So you see sir that that he himself injected a comment that had little to do with his own thread. I was just pointing out that part of GMs trouble is related to some of their failures to change.

A minority of members carry so much anger that they have to resort to cursing. It is ok with me, I know times are tough but it makes little sense to lose your credibilty even though the thread was briefly misdirected.

If every audiophile purchased class D amps, it still would have little effect on the enviroment since we as audiophiles represent a small segment of society. You buy what ever turns you on but my final comment that there is a downside to both tubes & solid state holds true and it's just a matter of chosing whatever turns you on.
