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 have the HD 600s and find they are wonderful. I use the MG Head OTL headphone amp. For me they are better than any stereo system I have heard with more detail and nice weight and decent bass. I have more experience w. Speakers and Amps but it sounds like Headphones are similar in that they need to be matched to the amplifier driving them.

I have not tried any other headphones besides Grados for comparison. The Grados sounded great but very uncomfortable to wear long term for me.
