Sorry, not having read enough of this thread, I may be repeating something here. I owned a Threshold S500 and took a peek inside. It was impressive, 'for it's time', I will say that. As well built as it was, there was an issue with the channels being cooler than they should, which is a bias issue. My point here is that to resolve all the issues associated with getting the amp back to spec was not worth the effort. The search went on from there to find a suitable working replacement.
Threshold verse Pass Labs how can I justify significant price difference
I'm running currently series one Threshold S500 with the optical bias and Threshold S500 second series as a bi amp config to my JBL 4367. System sounds the way I like it no complains.
Now I've been having thoughts about upgrade amps to Pass Labs 350.5 or 250.5.
250.5 would be in same power range as S500 so my question is since Pass will be priced higher how much better would it sound and is it worth to spend extra $$?
does 250.5 will make so much difference that there is no sense to go up to 350.5? or the only way to get any significant upgrade is to go for 2 of 350.5 and would it be so much better sound than my Thresholds I could justify spending extra $7K!
Can't wait to hear what you guys have to say.
