Headphone amp for Sennheiser HD600


Any recommendations and where to get them? Are there any other choices besides Headroom?

Yes, check out Audioadvisor.com I got a sweet deal on a pair of HD600's and a Musical Fidelity "X CAN" tube amp as a package deal. I cant remember what I paid, I think it was around 500.00 for the set. Call to get the deal.
Gundam91: I'll be doing an extensive test of Grado RA-1 headphone amp with the Grado RS-1s vs Sen 600, which I have on order from Germany.

I also have just purchased a Placette active line stage preamp, which contains a class A headphone amp. In a preliminary 2 hour A/B against the RA-1 (which in itself is a very, very good headphone amp) the Placette totaly smoked the Grado. Most pronounced, was "less jumbling" of complicated treble pieces -- the Vishay resistors really add nothing to the source and there is absoultely no distortion on the high end. To be fair to the Grado which costs about $325, the Placette retails for $4000.

The Placette is especially gradifying with SACD, XRCD and other high end recordings where there is little/no digital edge to contend with, as I do not have a DAC (source is an SCD-1). As I spend 50% of my time listening to headphones, I take this stuff very seriously, and my current setup is very close to some of the better STAX setups I have heard, including an older Omega I system. --Lorne
I have a set of HD600 connected to a Headroom Max amp. It is a bit expensive, but it sounds fantastic to me. I use an Anthem CD1 as the source for this setup, it is what I listen to in the office.
