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 can not believe anyone would not be bowled over by the 650's. They have become better still after being played for some time, however, even new they were wonderful. I've heard them on OK components, and state of the art stuff, and although SOTA stuff sounded better, the 650's are always wonderful.

There is something very wrong here, I have heard of HD650 copies getting around, also B stock from the factory, maybe yours could be one of these.
As mine are simply stunning to listen to. And the only headphone that I have heard to just slightly better them were the HD800's and not worth the extra double or tipple the price

Janeb, I had the X-CAN V3, and I found it to be totally underwhelming. Try a new headphone amp.
