Kick butt. What a joke.
Set that old tube amp out by the curb, and you'll be ahead of the rush.
Class D is already starting to make such amps worthless sonically and in time, in terms of valuation. In a couple years such amps will be fairly worthless, and rightly so, as they will have slid from occupying a status of HiFi to MidFi. Class D is now so good that I would not dream of using any amp, SS or Tube, over five years old. It would be a waste of my time to even assess such amps.
I predict that in a couple years those who are serious about an assault on SOTA will be looking to Class D to achieve it. Those who want a bargain will be looking to the other genres - an inversion of the historic norm regarding amps. It's going to be come bloody among amp manufacturers going forward. Not that I wish ill on other SS and tube amp makers, but such profound technological and sonic progress will not be impeded by nostalgia. The only justification that one might have to use an old tube amp will be that it is cheap. Looking at the other two threads started by the OP with the same dismissive statement, that is perhaps the motivation of this thread - pretend old, cheap gear performs as good. :)
SOTA sound is changing for the better right NOW, and Class D is a primary driver of it. Class A, A/B and tube amps? No, they are doing nothing of the sort. The glorious future of Class D amplification HAS arrived, and it will only get better! Cynical? Skeptical? You lose out.
