Pass Labs xa - .5 amps

I must bow to the respected Audiogoners that have personal experience with the Pass amps, but, I was under the impression that the special design traits of the Pass amps benefit even more so from balanced use than is typicaly the case with other amplifiers.

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... (?)

I have used both the XA-30.5 and XA-60.5 on my 93dB/8 ohm speakers, and there is not an appreciable difference in sound between the two amps in my system. The XA-60.5 just play louder.

If the XA-30.5 aren't creating the sound you're after, I don't think switching to the XA-60.5 is going to result in a worthwhile change.

fast reply ;-)

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

The Pass Labs XA-30.5 and XA-60.5 don't display the shortcomings in my system that you describe, and since I'm not familiar with your system, room or listening preferences, I can't offer an alternative based on experience.

Just for something to research...I've never heard the amplifier myself...you might do some reading about the new Modwright KWA 150.
