You should look at Head-fi.org for more info. I use a Bottlehead Crack with great result with my HD650. I know they are not 800 but its all i can afford. Anyway i have try some SS amps and for sheer musicality tubes are better. I havent tried the HA-160D but its a very good dac/amp from what people are saying. With SS my 650 sounded bright and digital, but when i tried the BH Crack, it was music like it meant to be.
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.
