I have been using Pass pre-amplification (X-1 and X-ONO) and have loved the combination, so I can't say anything bad about Pass Labs. The entire X-series has received pretty much universal applause. But if you are looking for bass slam and mucho dynamics, I don't think you can do any better than the McCormack. My DNA-225 has power reserves out of this world, belying the 225 power rating. The DNA-2 is even more of the same.
Neither amp, that you are considering, is particularily known for its airness and sweetness. Detail and power sure. The DNA-125 and DNA-225 were steps toward sweetness with detail. And the new Pass Labs XA-250 is promised to be even more of the same.
I hate to say it but your best bet may be listening to both before committing. Even though I don't think you can go wrong with either. One question though: How much power do you really need? A used DNA-125 would cost you even less as would one of the earlier Pass Labs Alepha series.
Best of luck,
