I'd be interested in joining. I've owned the Turbines before, and liked them very much. I primarily listen to rock, with a bit of hip-hop. I buy all my music in CDs and rip them in lossless. My home amps are way too loud for IEMs, so I would listen to them using a Samsung P3, Sansa Fuze and Clip+, as well as a NuForce Icon Mobile via USB.
I usually use full-size headphones and amps for listening at home, but on the go I'm using Phiaton PS200s at the moment, as well as Sennheiser HD 25-1 IIs, both of which would make a viable comparison. I've written a few reviews before, one on the PS200s and another on the Turbines. You can check them out at HeadRoom (headphone.com), under the same username.
Thanks to Monster for putting this generous opportunity out there.
