Pass Labs xa - .5 amps

Hi

I'm normally running Accuphase DP-67, C-275 and Krell FPB 300CX on my Vienna Acoustics The Music. My goal is to get some more body voices - the bass with the Krell is fine ;-)

I have tried Pass XA30.5 in my system and I especially like the midrange and the involvment. What I don't like is a rather slow and to heavy bass. The speakers are 4 Ohms and sensitivity 91 db. They have three 9 inch woofers pr. side.

Can anyone comment on if XA60.5 would solve the issues I have with the XA30.5? It's bigger amp but I have read here on Audiogon that the sound is very similar - they just give a possibility to play louder... (?)

fast reply ;-)

Tvad, what would you suggest? A fuller sound compared to the Krell 300cx but with most of the bass control in place.

;-)

Soren,
I have the XA100.5. I used to have the XA160. In my system, Eggleston speakers 87dB/6ohm, the 160s were a little slow/heavy in the bass as you describe. The XA100.5 has much faster, more articulate and defined bass and are better balanced overall. Great control over the woofers. The mids on voice and strings are exceptionally involving - lots of body and presence. I have not heard the XA30.5 or XA60.5. Matching a pre to Pass amps is very important. I auditioned a very well regarded tube preamp which sounded terrible in the bass region with my amps but great in other systems.
