Tube Watts Vs. Soild-State Watts?

The only way to know the difference to YOUR ears is to , in the words of NIKE, "Just Do It". I could go on and on about the advantages and disadvantages of each, but that would tell YOU nada. Your motors may prefer one or the other. Unless they are ribbons, electrostatics, planer magnetics, or very difficult loads, I would advise giving tubes a try, especially if they are very efficient. Wouldn't kill you to experiment, might cost you a few hundred $ in flipping if you dont like the result, and even that wouldn't impugn all tube amps based on one experience. Just sayin'.

I’ve nothing new to add to the discussion. I try to see it simplified.

1. You need you solid state amp to not distort. That’s why you should buy as powerful amp as can. Unless you don’t listen very loud.

2. You don’t need as much power from you tube amp since it sounds nicer when distorted. As always more power is good since distortion is bad.

3. If both (good quality) amps are run within their limits they will sound very similar.

And with that in mind I chose a powerful solid state amp for my system. Mostly because high power tube amps are really expensive. ...but an 80wpc tube amp would easily drive my system for 99% of my listening. :)

I finally got my transmitter amps and hooked them up to the Double Impact speakers. Glorious sound, very detailed yet rich. I was afraid that I would lose some bass coming from the large solid-state amp that I had before. That was not the case, bass was quite impressive and plenty loud.
Now the bad, after a few hours of use, the right channel suddenly dropped in volume to about half of what the left channel was playing. I replaced the input tube but that had no effect. Is this a tube problem, or something else?
