I just reread his OP and I do believe you are correct.
If that is the case, I wouldn't even bother and get a XPA-3 instead.
You can find a used one for close to the same price as a new UPA-500.
:) No question.... :)
Can't disagree with any of that really.
I'm not making a subjective claim of the sort where opinion is presented as fact. I have been careful to point out that I do not really believe that SS equipment needs to 'warm up' before it sounds right. This is quite different from what I understand as subjectivism where someone says words to the effect "SS equipment sounds better after it has warmed up and nobody can show me otherwise with their measurements and science". That is a very different sort of thing to what I am saying. For all I know, my Class A amp might measure better after it has warmed up, even though I believe it is unlikely. I would love to know the truth about this and I may yet measure the amp myself.
The problem with subjective claims is when people present them as fact and others then go out and waste their money believing that one SS amp that is working properly and within its design limits sounds better or worse than any other subject to the same caveat. Same with DACs and cables.
Some people have even been known to deny proven objective reports about the failings of well-known equipment, even when those failings have been acknowledged by the seller of that equipment! Imagine!
Yes, probably a good idea. I expect that one day it will cease to function. If/when that day comes I don't whether to consider it a blessing or a nuisance. WRT to blessing, it gives me some inspiration to review and revise my stereo system. I don't think I have much interest in m/ch music (I have over 1000 stereo CDs) so a new 2-ch system in that room would be something to look forward to. WRT to the nuisance, well there is the cost of course and also the concern that I will not be able to get that sweet sound I have grown accustomed to. Could be interesting. Of course, if all I need is a few replacement caps, then it could be repaired and go for another 20 years :)
It looks like they fixed the problem, XPA-1L is on sale :)
Let us know how you like it, I wished there was a way to find out if it really does Class A
