I use to run some paradigms. I was using their statement amp with a 3k denon receiver as a preamp . Switched to a paradigm avm30 and heard a huge difference . I think a different controller or a dedicated preamp would make a big improvement for you as well .
Should I add a stereo preamp?
I have Paradigm S4 v1 speakers driven by Emotiva UPA-1 amps. I am currently using a Pioneer Elite VSX23. Would something like a Parasound 2100 improve 2 channel performance compared to the receiver? I am using a sub and everything is connected to the receiver digitally to avoid adc to dac for using the crossover.
