Thanks. I do tend to enjoy coming into work a bit more than I should.
The best I've heard so far. I've run them through an Icon HDP, Anedio D1, SinglePower Slam PPX3 6sn7, DNA Sonett, and regular WA6SE. My ranking is WA6SE maxxed > Sonett > reg WA6SE > Slam > HDP > Anedio. Not a big fan of the Anedio/Saber sound.
The key thing is they're pretty closed in headphones, I run the Woo w/ 6ew7s and esp. an EML 274b to blow up the soundstage. Important when you use them 4+ hours every day. The EML really makes the key difference - tried a miniwatt GZ34, Sophia Princess 274b, EML 5u4g, and the EML 274 is where it's at for me.
