Hi, I've been a reader of this forum for a number of years now and I just decided to join and start posting. I really enjoy listing to music through headphones and I always seem to have upgrade fever.
As I work out of town the majority of my headphones are portables: PSB M4U2, B&W P5 (haven't used these for a while), SONY MDR 7520, Kef M-500, Sennheiser Momentums, SONY MDR 1RNC (don't care for the 1RNC's at all and I never use them) and Sennheiser ie80's. I also have a pair of V Moda M-100's on order which are supposed to be here on Thursday.
I received my Vamp Verza yesterday and tried it with my Kef M-500's, my Momentums, and my Sony MDR-7520's. It seemed to make the biggest difference with the Sonys. Personally, I had found the 7520's a little bright, or maybe just kind of boring until paired with the Verza. I had tried the 7520's out of my Audiolab M-DAC as well as straight out of my iphone/ipad and never really enjoyed them... until now.
For home use I run my M-DAC into a LYR with HE-500's. I am hoping to pick up some LCD2's one of these days as I really enjoy the HE-500's but I do find them fatiguing at times and depending on my mood I like to have different options.
