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

I used to own Pass and Eggleston Rosas. Pass and Eggleston are a great combination. I found the more power I had with my Egglestons, the better they sounded.

My buddy Madfloyd just upgraded from the XA160.5 to the XA160.8. I heard both in his system two times. The .8 had much better control of the Alexia's bass and the overall sound was more transparent. I think the .8 also has lower noise so more information came through. I really liked the .8.

Dave 72, First impression. Pretty good...
Deeper soundstage, better bass and treble. Even at this early stage, I'm sure its a keeper.

Hello Ozzy. Can you compare it to the XA series if you have heard them? I'm looking for the liquidity and naturalness of the XA but the dynamics of the X. I'm actually waiting on a X350.8 too. Have owned/demoed the X150.5, X250.5 and the XA100.5. Many thanks.

Thanks for that, Ozzy, it definitely helps me out. I look forward to your full review...

I've had the Pass X350.8 plugged in now for about 5 days. Playing time is about 10-15 hours.
The sound stage is deep but seems a little dark. That is, with little air around the instruments, and the treble seems to be a little muted.
Though this somewhat concerns me, it is probably normal for the amount of time on the Amp.
