Audio Research Ref 150se vs Ref75se on Martin Logan Renaissance 15a.

I have purchased new pr ML 15a spkrs. I own a Audio Research Ref 75se which seems to have no issues driving the 15a's in terms of power output. The 75se isn,t clipping or even coming close to it the 15a's are 92db at a 4 ohm load. What I'm wondering is taken the Ref 150se's much larger power supply and larger power transformers will this prove to be a much better match for the ML electric static panel? Will I hear more highs,control and definition with the larger power supply?
Example at lower volumes will a larger power supply improve the dynamic range of the E.S.P?
the spkr is rated a 4 ohm load but dips below 1 ohm at 20k.
So since the 75se isn't coming close to full power output even at high volumes will the 150se be a better match?

 I have the 75SE and auditioned the 150 before I bought the 75. I definitely preferred the sound of the 75, especially when I upgraded to the SE status, with KT 150's. So for price and sound quality, I'd go with the 75SE.

The 150 may well be better on the ML's, the only way is to borrow one from a dealer, if you can and see. If auditioning is difficult, I wouldn't
shell out the extra on the 150, if I was happy with the sound you are getting now
