Sony MDR-E484, E888, E565
AT-W2002 (w/ L3000 drivers)
Senn HD-580, HD-580 Jubilee, HD-600, and HD-650
Shure E5c and E4C.
I'm done.....but the HE-90 and HE-60 w/ Singlepower electrostat amp will be very nice. I had the Baby O system in the past and didn't really like it that much. My current rig sounds absolutely wonderful right now. I doubt my headphone system can sound that much better than this.
Grado RS-1/2 (I feel myself moving towards the dark side...)
Sennheiser HD650 (Just like I don't buy into the whole Dog-person, Cat-person thing, I don't buy into the Grado-person, Sennheiser-person thing either..)
A pair of IEMs: thinking about Shure E4cs.
