I imagine different quality amplifiers can have a different sound within your system possibly, but wonder if it is not advisable. I have Anthem AVM70 processor, and 2 of their amps(MCA 225 GEN2 & MCA 325 GEN2) unboxed. I was considering adding the Parasound A21+ for the 2 channel only when just listening to music simply because I am having a hard time seeing myself spending 6K for the Anthem STR amp. I don't have the speakers, however they will be the JBL HDI 3800, 4500 &1600’s with a couple of Atmos speakers undetermined at this point. I already have dual FV15HP RYTHMIK subs. I realize I’m going about this ass-backwards and it’s too late As I already invested in Anthem. I will have everything NLT mid May. Worst case, I’ll suck it up and get the STR maybe a little later due to the cost. Thanks for your help.
