Chess i thought the same way and i can not explain it but when i added my Emo amp to my Denon receiver it was like a window had been opened. Was it expectation bias, i have no idea and wish i had introduced it differently with more A/B but thats no how idid it. When i went to seperates i found nirvana and honestly have no desire togo beyond my M80's though i did add qs8's a while back and that was awesome. I hope you can find your nirvana as well. My next quest will be some Mid Bass modules for the gut punch i really like but i need to get it without playing at high levels, im just not wired like i was when i was young and dont like it as loud anymore. Bass is easier on the ears.
