As a new member I'd like to get opinions on the best sounding opamp/buffer combination for driving HD600 phones.

Thanks

The amp will be mains powered so there's no quiescent current issues

That's a hard question to answer. So I will give you more than one choice.

Now, according to ppl, the AD843 and the EL2009 combine to make the best opamp/buffer combination for a headphone amp or preamp. The EL2009 and EL2008 are discontinued and hard to find. However, Tangent sells the EL2002 at his Audilogica site.

Therefore, I would go with the AD843 and EL2002.

TI-Burr Brown Opamps...
OPA627
OPA637

Analog Devices Opamps...
AD843
AD825

Elanted Buffers...
EL2002
EL2008
EL2009

Good luck with this info!

The ad8610/20 aren't too shabby, either. If you cannot locate the el2008/9, use a stack of (2-4 min.) el2002's.

Definitely stay AWAY from Burr-Brown op amps when using the Senn 600s!!! The AD stuff tends to help with the midrange a little bit more and have a better sound IMHO!!! You want to pair up some good AD stuff like the 8610 for single channel, or 8620 for dual channel, or go with the AD843 or 825s. LC Audio sells some modules that come with the 825 and some decuopling caps that really sound nice in my set-up.


I'll let someone else speak about the buffers as don't have any experience with them myself.
