Crown Xls 2502


Considering adding a crown Xls 2502 to my denon 4520ci. Not impressed with clarity of my revel f12s at high volume(-5db & above) with the denon amps-even with the revel b1 subwoofer engaged to help.

Improvement? Or am I experiencing the speakers limits?

The 4520ci was bench tested 173 x2 8ohms 0.1 thd/237 x2 4ohm 0.1 thd.

My setup is 2.1. Thoughts?
