What headphone amp to use with Sennheiser HD800?


I just bought the new Sennheiser HD800 headphones and I would like feedback from other HD800 owners. Which headphone amps have you used with the HD800's and which they selected and why? I live in a very remote area and I am about 300-400 miles away from the closest high end audio dealer. Your suggestions and comments would greatly be appreciated to help me in choosing a headphone amp for these incredible headphones.

Woo Audio WA5-LE with Sophia Royal Princess 300B, EML 274B, and Sophia 6SN7 tubes. Highly recommended.

I used a Creek and did not like it as well as the Musical Fidelity amps. Creek may be better for Grados.
I use the Bada hybrid headphone amp with the Sennheiser HD600s. The Bada is exceptionally neutral, dynamic and realistic and responds quite well to tube rolling. While the stock Chinese 6SN7s in the Bada are surprisingly good, NOS RCAs and Sylvanias are magical.
You cant go wrong with the HA-160D!
you can also find lots of positive feedback about it when paired to the HD800's.
