Bump,
To anyone who is thinking about it -
These are
reference grade headphones. Most will never need to upgrade, until unless you are a headphile and looking into the far edge of the spectrum with the SR-007 or 009 (and of course until unless you have an excellent front end!). Pair it with the USB Brick DAC (also up for sale), you won't be looking for something more anytime soon

Unlike electrostatic speakers, this is true full range. Open ear headphones also add a semi open baffle effect

Perfect for office, apartments and small private late night listening/quite sessions!
A model below this is issued by Smith analyzer, 0202 I believe!
Again I'll work with you on a combo deal with the DAC. Local pick-up So-Cal/LA area, even better ... I'll bend over backwards for yah!
Cheers,
VJ
