Subtantial improvement over Emotiva XPA-1's?


I'm considering upgrading my amps, Emotiva XPA-1's. My options at the moment are: Clayton M300, Theta Citadel and maybe Mcintosh MC601. My speakers, Tyler Acoustics D1.
Do you think is it worth the extra money? Is there going to be a HUGE improvement in sound?
Thanks for your help.

I'd go with tubes and not worry about the D1's bass response. Supplement with a small sub/s that would have control your rooms bass EQ.

You'd end up with the lushness of tubes and deeper more controlled bass.
I'm really considering a pair of Rogue Apollos monos with KT120 tubes... Any comments?
Love my Rogue Stereo 90 with KT120s. It is back at Rogue now getting updated to Super Magnum status.
I vote for the McIntosh MC601 monoblocks, regardless of what type, brand, or spec speaker you have, the MC601 will bring out the best out of the speakers you have.
