McCormack DNA-1- improvement over Bryston 3B NRB?

I just purchased a preowned pair of Paradigm Studio 100 v.2 speakers (and despite the mixed reviews these get in the forums here, I love them), and despite the fact that my trusty Bryston 3B NRB that I've had for 10+ years drives them with no problem and sounds just fine (125w into 8 ohms), I've really got the bug in me to get a more refined, and possibly more powerful amp. Would a McCormack DNA-1 fit the bill? If not, what would be some good recommendations? Is it the ideal approach to try to acquire a higher wattage amp? Thanks, Will
