Pass X-250 or McCormack DNA-2 Deluxe


OK, here is my question. Do I purchase the Pass X-250 or the McCormack DNA-2 Deluxe, both would be purchased used (Pass $3K-$3K, DNA-2 Deluxe $2K-$2.5K)?

My system consists of Sony SCD-777ES, AZ Silver Ref. ICs, BAT VK-30SE tube preamp (probably upgrade it to 31SE) and B&W 803 Matrix Series II speakers. I want the sound to be sweet, very fast, detailed, airy, smooth, extended, slight warmth, bass slam and mucho dynamics and more.

Has anyone compared these amps?

Thanks your input will be well received.

I'm just wondering how you narrowed it down to these two, if you haven't heard either one? Thomas is correct about auditioning before buying if you can, and I don't hate to say it. :-)
arn't we talking about two different price levels?
i would add plinius sa250 in that list which is superior to them both.
if you can't stretch to plinius SA250 you can get SA100 which will bring you everything you've just stated into your speakers.
The Conrad Johnson MF2500 will also provide the qualities you seek and it works great with tube pre-amps. However, you really should try to audition if possible before you buy.
I dont' think the McCormack (even with the expensive upgrade) is in the same league as the Pass. My Opinion. Also do some research here, you'll see.
