Pass Labs x150.5 question

Just to exemplify my personal experience.
Dynaudio C2 + Accuphase amp = great bass but otherwise too rounded and soft for my taste.
C2 + push-pull tube integrated = no go!
If I had a pair of C2 then Pass X series or even Krell would be some of the first to try.

Absolutely..Ive run that amp through C1s and C4s.Yes I agree that the 250.5 would be even better as Ive done that as well but the 150.5 can hold its own with those speakers(300 watts into that 4 ohm load I believe)..Pass labs and Dynaudio are a super match IMO.Im not real crazy about your pre amp selection though.

I already own the McIntosh C220 preamp and I like it. I'm losing a McIntosh amp I have been borrowing from a friend. Have you heard the C220 preamp or are you saying you aren't crazy about paired with the X150.5?

The Pass X151.5, aside from great sound, has more power than you might think. A British hi fi mag about 2-3 years ago tested it and found that at 8 ohms it clipped at 280 watts, IIRC, and at 4 ohms 370 watts, again IIRC. I had no trouble driving my Magnepan 3.6's with it using a passive preamp.

I have an x150.5, it replaced a higher wattage Cary ss amp. It's driving Piega C8's (ribbon tweeter, 4 Ohms, 87 db). It rocks. Got more low end that the Cary and is smoother in the mids. The Cary had some screamin' trebile though...(read: totally unballanced)
