You hopefully just need to give it time to break in. Dont do anything(else)hasty till youve given it a bit of time. Good luck...
This sucks
I just liquidated my old system [http://forum.audiogon.com/cgi-bin/fr.pl?vstrt&1125889203&view] and replaced it with the follwing: Marantz SA8260 (on Mapleshade Surefoot), to Purist Audio Maximus ICs, to Cary 300SEI (on Mapleshade Heavyfoot with PS Audio Lab I PC and Sophia 300b) to Blue Dragon headphone cable to Senn HD650. There is NO bottom end and the whole soundstage sounds smeared and just overall horrible. What the hell was I thinking?? Is there a link in my current chain that might be causing this?? Is this the best I can expect from my headphone system?
