To Tube or not to Tube......


For quite some time now I've been thinking about switching from a solid state to a tube power amp. My Threshold T-100 has been real good to me and I do like it, but it's really the only "high-end" amp I've ever owned, so it's all I know. I'm intrigued by the "warm" sound of tubes and do have a tubed phono amp and CD player, but I am by no means well-versed in the sound of tube power amps having never really auditioned one. I know that goes against the prevailing wisdom and I should listen before I buy, but I don't think I will have the luxury of doing that.

That being said, I've gone through about 20 pages of this forum reading about the benefits and detriments of tubed power amps but nothing I've read has swayed me either way. The posts I've read have been informative re: bias issues, reliability, blowing fuses or whatever else might blow up or go wrong with the tubs, etc. So, if I were to go the tube route, I would not want deal with too much of that hassle. At lease I know that the amp I have doesn't have any such issues. That's why I was leaning toward amps like BAT with their auto biasing (I also need balanced inputs), and would want at least 60-100 wpc. I would be willing to deal with adjusting bias so long as it was a relatively simple process.

I figured I would pose my main question to the exerts here (and this I did learn for this forum): given what I already have in my system, what tube amp would be a good match for me? My pre-amp is a SS Threshold, JM Lab speakers with a "minimum impedance of 4 Ohms," EAR 834P phono stage, & Unison tube cd player.
Much appreciated.

Unsound, when you only know one thing, it's hard to say what you don't like. It's not that there's some thing about it that I dont like, per se,it's just that its all I've know. I want to try something different, and tubes is the way I want to go.
How did it compare to live music? Just trying to steer you towards an amp that might satisfy you, even within tube amps, there are different sonic personalities.
I would say that the T-100 did have a nice sound, but if it was lacking anything it would be in the areas of separation and perhaps sound stage.
Ebuzz, EXACTLY!
I understand that tube desire can be so strong that owner is willing to sacrifice system performance(seen many cases like that) and even make themselves believe that sound became more 'natural', but the fact will always remain the fact.
All I can say is, Curiosity killed THIS Cat. I was pretty much like you.
I had an older Audio Research D120 ss amp that was recommended to me by a dealer (thanks Tim!) over newer and more expensive ARC products. With this amp hooked up to my Berning preamplifier, AND with appropriate cables, I was getting 90% of what a VS115/LS17 was producing.
But Nooo, I had to be a greedy audiophile who wanted it ALL.
So, I sold the D120 and got a D115 instead-Supposedly one of the all-time greats..
The result: A warmer, narrower soundstage, with increased smoothness in the upper midrange and enouch HEAT to make Satan squirm. Now, my Proacs no longer dissapear; and there is a distinct loss of detail, neutrality and Bass SLAM.
So, after 700 bucks spent in replacement tubes and repairs, I've made a step backwards and wonder why I did it...
