I have them hooked up to a schiit bifrost uber/valhalla and listen to 80s metal and rock all the time. It really depends on the rips and source material. Sometimes the original source wasn't that great to begin with. I'm not an audiophile, but I know that the combo I have is the best I've heard ever and see no reason for myself to buy something more expensive. I did order a toxic cable that should help it sound even better.
