I am more curious how an Amp / Pre-Amp vs Receiver will effect the sound or perception of sound from a given set of speakers.

I quite honestly like the speakers that I have, and have ZERO plans to replace them at any point in the next long while. If you are happy with what you have, then looking at what other people this about other speakers and how they sound is a little bit pointless.

Anthem: AVM60, Fosi DAC-Q5
Axiom: ADA1500, LFR1100 Actiive, QS8, EP500, M3, M3comp, M5
