When I'm on the jobsite loudness is #1. At home fidelity is first and placing speakers in room optimally is as important as mating them to a suitable amp. Anyone that thinks all amps sound the same is welcome to come over and listen to my 3 integrateds with similar power ratings and agree the differences are there, but could fall into the class of different, not necessarily better, then listen to the final set up and try not to be stunned at the improvement. Sometimes I do wonder if a preamp can be detrimental. I haven't met a single dealer that tried to convince cables made a significant difference. With my Roon nucleus there I have 1 dac I prefer MQA 24/96 to and another dac I prefer the flac 24/96 recording of. ones tidal and the other's qobuz so that's another variable, and the difference could be compared to opening or closing the drapes, so take it as you will.
