I found out about this guy from head-case.org:

Robert Levi has also been known to make outlandish claims such as the PS1000 having "supreme neutrality, and ultra linear frequency response" and being able "outperform" STAX electrostats"; and the Ultrasone Edition 8 as having "the flattest sounding, most extended headphones I have ever heard" when subjective impressions from those with considerable experience with those headphones and objective measurements say otherwise.

I don't know what kind of koolaid or drugs that guy in on; or perhaps he's really a shill, readily accepting hong-bao from audio companies - or maybe he's just a retard. He does seem to be a fanboy of E.A.R. and Modwright, but this isn't too bad in itself. However, looking at his equipment list, it's quite obvious he is very susceptible to snakeoil products such as expensive power cables, quantum noise disruptors, Bybee filters, etc. which are nothing more than placebo.
