Hi guys:
I have confirmed that the Ref 150 is a replacement for the Ref 110. The Ref 110 is enough to drive the Sashas, but the 210s do drive them better--more transparency and better bottom end. The Kt 120s are very helpful with the Sashas. The 210s are 10 to 15 percent better than the Ref 110 if I had to hazard a guess at the degree of improvement. Worth double the cost?
