BTW, I got to try my HD800 powered by a WA3 with Chatham 2399 power tube this morning. I admit it sounded very nice - very similar in mids and treble detail to my DAC1 only "wetter" if that makes sense. My Benchmark just sounded a little "dry" in comparison. Of course, the bass was a little bloated on the Woo, but I guess thats to be expected from an OTL amp.
try a 7236 tube (tung sol/sylvania), they're a little tighter than 2399/5998 if you're looking for less bass bloat.
