Headphone amp for Sennheiser HD600

In my most humble opinion there is only one amp for the Sennheiser HD 600 headphone, and that amp would be the Wheatfield HA-2 tube amp, I am a lover of that glowing bottle. Have been using one in my system for well over a year. One must sample this amp to truly understand what it can do to headphones. I will say there is no substitute for the main system, but, when the requirements are that my house be quiet, I do use it with great success and infact look forward to the session. The Headroom people are the sole sellling agent of this amp. Good luck.......

I got both the X-Cans & Creek SE amps from AA for a couple weeks. The X-Cans worked a little better w/ these cans. However, REPLACE STOCK TUBES ASAP W/ AMPEREX NOS and now it is no contest. Either Bugle Boys or A-Frames softened the Tizzy sound on some mainstream recordings while letting great extension come through. Incredible difference in the bass w/ the NOS tubes. Much deeper and tighter bass. These cans are very easily tweaked w/ interconnects too. I either use the Harm Tech Pro Silway MKII or Cardas Golden Hexlink 5C w/ them & again it takes it to another level.

Thanks to everyone for excellent advices. Although the Wheatfield is a nice amp, at over $10K, I think my wife would hang me before I finish listening to my first album. EarMax, MG Head, and X-Can v2 all seemed to be good contenders with MG and X-Can at roughly the same price.

I am leaning towards the X-Can as I have a huge collection of 6DJ8 NOS tubes available already.

I got it confused! I was thinking of the Sennheiser tube amp that I saw at HeadRoom's website for $12,000!

I have been using a CReek OBH-11 with the updated power supply with very satisfactory results. The Sennheisers are
going "at market price" of around $350 new so a "package deal" with amplifier maybe your best solution.

Another option is to find a good tube amp or integrated that has a headphone jack. ( CARY - AES, ANTHEM etc.)

The HD580 headphphones are almost as good and if you can find them they are going for around $200.
