My RS-2 rig is the best I have ever heard. I use it with a special CMOY amp. I prefer this rig to my PS-1, HP1K, HD800, etc. Perhaps the pair you had did not have the yellow pads with the quarter mod? That makes a huge difference. Also, you should use a flat head screwdriver to pry off the button on the RS2 - that button really holds back the sound quality. Cheers!
