Pass X-250 or McCormack DNA-2 Deluxe

My vote also for Pass X250, Mccormack sorry in my opinion is not in the same league, email me direct if you have any question.

First, with the high-end system you have and money your looking to spend on an amp, I wouldn't make any decision on an amp without auditioning them in your system and home. You're mixing a tube preamp with a SS amp, so (while rare) there are tech. issues that may impact performance and proper matching.

Instead of these huge single amplifiers, you may want to consider biamping with two smaller amps. Bi-amping almost always yields better results.

As for McCormack versus Pass, I think the McCormack offers great value, but, for elite systems, the upgrades are a necessity. The Rev A Gold upgrades put this amp in rarefied air (the Gold upgrades being the key to super elite performance). You can't beat Pass craftsmanship though, so either way I think you will be happy.

Thanks for all of your responses. I wish that I could audition the amps in my system but since the McCormack is not a current model, the seller is not interested in sending it to me for a home audition.

Everyones comments were well received.

Thanks again.
