the Senn HD800s I got here used (w/ cardas blue cable) love being driven by the TubeDac-11.
i'm going through all of my half dozen tubes again and so far land back on the "russian rocket", sound is also very good from the tube out through my hr2, so I have a huge range of "flavor" changing capabliity. depending on the recording, I am liking the sonics straihjt outta the tube out more than through the hr2, but on some things the difference favors the hr2. could live with either very easily. the td-11 proves itself to me again as it rises to the occasion to drive the higher end cans i'm tryin with it now (the hd800s and a pair of Beyer T1s), I love this unassuming little beauty. You do not have to spend a fortune to drive the HD800s to glory as the TD11 is less than 400 bucks and the voshkod tube is less than 30 bucks.
..really appreciate those impression, analog'd.. I'm in the process of looking for/buying an HD800, as well, so the timing is welcome. Good suggestion on the (Voshkod?) Russian Rocket tube.. I've read very good things about it.. might give it a shot once my TD-11 is back (it's getting modded, atm).
I'm intending to the same as you: running the HD800 from the TD-11.. though I might use the Lake People G109 as a ss power amp downstream the tube out to get more voltage. But I'd prefer to drive it straight from the tube outs, though. Does the TD-11's tube outs alone swing enough voltage & deliver enough to get the HD800 to not just sound good.. but shine? One thing I've always appreciated about the TD-11's tube out (and solid state out, for that matter) is how silent the background is.. one of those things you have to 'hear' to appreciate, too..
Looking forward to more impressions about the TD-11 & HD800 if you have any.. cheers.
