Krell FPB 400CX vs PASS LABS X-350.5

Do you all think the smaller Pass Labs XA-30.5 would be enough for the Nines. My room is 14' x 24'?

Would that be a better choice than the X-350.5??

Well I actually had both amps side by side in my system for a while and the Pass X350.5 is better in every aspect than the FPB400CX.

The X350.5 should be compared to the Krell EVO402 and then they are very close. I had the EVO402 as well and it does sound very similar to the Pass X350.5 but at 1.5 times the price.

For price / performance ratio the Pass is the best.

The FPB700CX is much better than the 400CX and would come close to the Pass X350.5. The 700Cx might even have a little more bass slam.

I did a head to head audition between the X-250.5, the X-350.5 and the XA-30.5.

The smaller 30 watt class A XA-30.5 smoked both of the X models, and has more than enough power for my DeVore Nines in a large room.
