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.
