Sennheiser HD 650's thin sounding?


Just received a new pair of HD650's to replace my dead HD580's and they sound so thin!!!

I'm using a Headroom home headamp with a NAD 542 CD, Kimber PBJ's and stock HD650 cable.

What is the deal with these phones? My 580's had much more bottom end slam and bloom in the mid bass? Is it a burn in issue or defective phones? Anyone have a similar issue?

I agree that its unlikely that the 650s are the problem, unless of course they are counterfeit. I'd never describe my 650s as thin. Some might find them a bit laid back, but thin they are not. Never heard the X-can amp. Is there a possibility of an impedance mis-match btwn the can and the amp?
