What are the specs on each amp? Sound quality shouldn't change particularly unless that's related to power/impedance issues for your use/speakers. Feature or connectivity wise is there anything the change would satisfy?
Also, fwiw, I'd look at Buckeye amps for use of Hypex N Core modules. I don't "listen" to amps, tho, they shouldn't have a sound....
ps meant to mention I use some Crown class D amps that have been fine for many years (2 XLS1500s I got in '11, 2 XLS1500s I got in '13, and added a used XLS2502 about 10 years ago....
