Pass Labs Amp X350.5 or X350.8 anyone compare?


I have searched for some opinions as to the sound quality comparison between the older Pass Labs X350.5 which I own and the newer X350.8.
It looks like the .8 does not operate as much in class A as the .5. But, that doesn't tell the story.
Anyone have a chance to listen to the newer X350.8? And if possible how does it compare to the X350.5?

I've always had great service from Reno HiFi. Glad you had the same, Ozzy. I would expect nothing less from Mark. Someone will get a good deal on that X350.8 that Ozzy had for audition when it is sold as a demo unit at a reduced price.
I would try something smaller in class a. I had several JBL models loved em (after updating the crossovers and wiring) . Tried an x350.5 and it overshot the speakers sweet spot. You must listen very loud. I used Aleph 1.2 with my 4343 and I thought I overshot the sweetspot. Best of luck.
