Krell FPB 300cx vs Pass X250.5

Tpk123, it's been a few years already since I last compared a Krell vs a Pass Labs X-series amp, but even than, for my ears I found the Pass Labs to be a more musical/natural sounding piece. It had all the dynamics/slam of the Krell plus the above stated virtues. However, the new Pass Labs X-.5 series amps are not just slight improvements over the first X-series but a shift towards the sound of real music. They have much of the warmth/sweetness of the XA-series amps but the dynamics and power of the X-series. So to be fair I have not heard the latest generation Krell amps, but unless they have dramatically improved, my hunch would be the Pass Labs X-.5 series would still be the better sounding amps. I replaced a great sounding amp[Edge NL-10] with a Pass Labs X-350.5 because it just sounded more real and musical in my system. However, as you know personnal taste and system synergy always comes into play, so a home audtion using your ears is always necessary. Hope this helps.

Dr. Greenman, I guess its important to you that we know that you are one, it was not that long ago that I listened to Krell gear, but I know that Krell has changed to a degree their house sound, but my question to you good Dr. is, have you heard the new Pass Labs .5 series amps and how do they compare in your opinion? Also, have you heard the Pass Labs XA series mono-blocks which price wise might be a better comparsion, even though the 350.5 is a great sounding amp with much of the virtues of the more pricey XA series.
