I heard Purrin's pair at Frank Cooter's house last Tuesday. I used the Burmester CDII demo disc for my listening. The setup was a CD transport (older model, can't remember the brand) running into an AudioNote DAC into Frank's 45 tube-based amp. The headphones sounded nice, with the best bass I've heard from any headphones. I thought that maybe, just maybe, I occasionally heard a "resonance" in the left channel, but it easily could have been my imagination. Neither Frank nor I thought that the sound was veiled.
The only real negatives I have to say about the LCD-3 are that it's really heavy and it clamps way too tightly. Oh yeah, the price is too high.
Frank listened to both the LCD-3 and my HD800. He liked both quite a bit. I didn't have time to listen to my HD800 in this system. Hopefully I'll have another chance soon.
