Pettyfeversk,
Congrats on your new amps. I am sure that you would not have bought them unless they sounded great in your system.
Some years ago, I was auditioning a pair of Harbeth 40 Monitor speakers being driven by Rowland 201 amps. My mind had already been preconditioned to have negative feelings about the sound quality of class D amps, but when the music began, I was stunned. Listened to a lot of different music for about 11/2 hours, and I was completely surprised by the great sound. I am sure that the 501s are that much better.
