Need Advice: Which Headphone Amp?


Okay, so I recently purchased a pair of Sennheiser HD 600 headphones and now need a headphone amp. Can you give me recommendations? I have thought of the Antique Sound Labs, David Berning, Rega and Headroom. Are any of these are others good matches for the Sennheiser's. Thanks alot

How about a Cary CAD 300 SEI? Ok, it's overkill for just a headphone amp (though it may be the best one you can get... 300B outputs sent right to headphone jack) but you also get a nice 11 or so watt-per-channel integrated amp too...

FWIW,

You should check out Earmax too...many people love them with Senn headphones. I have a Grado headphone amp and it also works well with HD600's, but it's not a tube unit (nor does it sound like one).
The MF Can v2 with better tubes, Amperex, sounds very very good-- transparent. The SS Creek comes in a distant second.
