Hi Tylercoupe:
I have Ref 150 and Sashas and am quite happy with the combo. But as you know the Sashas are difficult to drive in the mid- upper bass/low midrange between the impedance and negative phase angle. I'd like more thrust there but at reasonable cost.
When I had WP 7s and tried Ref 110s and 210s. I found, as you did with Ref 150 vs 250, that the lower powered model came close enough that I stuck with the Ref 110s. The biggest differences I found were a greater sense of dimension and ease with Ref 210s. I did not find the dynamics on the 210s to be more than 10% better than the 110s. Have you tried both amps with Sashas? Can you quantify the differences esp in the mid/upper bass?
