I've recently purchased a used pair of Sennheiser HD650's (great condition), and I'm rather underwhelmed by the performance of these to be completely honest. Maybe all of the rave reviews gave me an unrealistic expectation.
I'm powering them with a Peachtree Decco65, also using the DAC to connect to my MacBook via USB. (i7, 8GB RAM, BitPerfect, etc)
Now I'll start off with the things I really like about these headphones.
Pros - Very comfortable (amazing), detail is great, very comfortable sound (not fatiguing)
Cons - Lack of separation (gets muddy with complex pieces), no stage whatsoever.
Could this possibly be my source of amplification? I figure its very possible due to the Peachtree not being geared for headphones exactly.
Any advice? Am I expecting too much? I've only owned the headphones for about 2 days, so maybe I just need to warm up to it. I tend to be disappointed with new equipment at first, and warm up to it over time.
