ok, no one can relate to me, or nearly agree with me yet....
alessandro ms2i w/ recable, and don't get a gilmore amp, get something with tubes like a ppx3 slam. I was kind of surprised how much i liked it.
controlled bass, not nearly as plentiful as ps1, but damn well controlled, more so then any rs1 i've heard personally. Balanced, more balanced then any other john grado headphone i've been exposed to (all of them). It had oodles of high end extension, smooth, yet not overly analyitcal.. Also, the sound stage, not like normal grados, maybe i ahven't heard recabled ps1s, but man, these guys got a sound stage, i listen to alot of electronic music, and though i wouldn't nearly claim sennhesier levels of channel seperation, you will turn your shoulder and sometimes freakout level sound stage...
They have authentic grado sound, added percision with the recabling, percise and fluid... The tubes will make everything so juicy and smooth, fluid controlled, extended... Very authentic grado.
Oh yea, and this definatley meets your 1700 dollar budget. The ms2i recable is a great value. They are great with dance music and electronic stuff. Yet, also for progressive and classic rock.. I hope you give the upgrade a consideration.
