My source is either a vinyl player or a Cowon D2 which both go through a rotel ra-05 amp. I'm not sure if it will help greatly to give a sample of the music I listen to, as my taste invariably changes with the seasons, but I'll list some artists anyway:
Currently I'm listening to a lot of IDM, breakcore, ambient type stuff - Squarepusher, Amon Tobin, Aphex Twin, Lorn, Loscil, Gas, Baths, Minecraft Volume Alpha, Burial.
And then I listen to assorted things like Can, Ty Segall, Elliot Smith, Roy Harper, Tame Impala. I could go on, I really am not confined by genre borders, I'll listen to anything that I can appreciate.
On my vinyl player I've started listening to Miles Davis and Coltrane, jazz is something I'm just starting to get into
I don't know what conclusions to draw from that list but I guess I like the ambience, textures and character that is evoked by a song or an album. So I think in my new headphones I'm looking for accuracy and high resolution throughout the entire range.
I'm not fussed about bass for the sake of bass, I've enjoyed the bass presentation of the M50s. With the M50s I feel like I might be missing the mid and upper ranges of music slightly. I'd like something to contrast against the closed sound of the M50s too, something more airy I suppose.
Beyond sound signature, I'm looking for comfort, I find the M50s can hurt my ears after a while (I think I need to replace the pleather pads).
Thanks in advance for your help.
