Class A headphone amp equal to Luxman SQ-38


I recently auditioned the Luxman SQ-38u integrated amp. While it didn't work with my speakers of choice (ProAc), it was absolute MAGIC with my AKG 702 cans. Problem is, I don't want to spend $6,000 for a headphone amp.

Any recommendations?

Thanks for the options, Jax - I'll look into them. That said, I think what I liked about the Luxman integrated was it's class A tube design. Music just seemed to flow naturally out of it. I think the AKGs are a little on the intense side and this pairing seemed to compliment each other's strengths - detail and staging yet warm and engaging.
Why not just get one of the dedicated Luxman headphone amps? P-200, P-1u. www.ttvj.com carries both and I think he has a return policy.
I only heard Sennheiser HD-800 and Grado GS1000 on the class A tube section of a Peachtree Audio iDecco. It was damn good. I suggest an audition. I'm planning to go that direction.
Given your description of the Luxman I'd audition the Eddy Current offerings if you can find one to audition, or perhaps the EAR. The Luxman headphone amp seems a natural as suggested. Though the Woo's are excellent choices too and posses some of the qualities you describe, I would not necessarily call them "warm" though they are all tube-amps. They do make the 702's sing though.
I have the Luxman P1u and a Leben CS300XS. You might want to audition the Leben, it has a wonderful headphone out and might play well with your ProAc's.
