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?

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.
Here is a link to the fake HD650.

Spiritualized, I'm pretty sure that your'e right regarding the X-can. I noticed today that the latest version has been removed from the market. I have come to believe that all Musical Fidelity gear is nothing more than mid-fi at best.
Yesterday, I heard a pair of MF Titan's at a friends... they were a joke, my friend is taking them back as soon as he can. Overpriced total garbage as far as I could tell!
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?
