Thanks guys. No Ed, I'm not looking to mod them. I bought the model with the wooden cups and upgraded wiring so I wouldn't have to mod them. But if I had bought some 80s or 125s like I started out to get at the beginning of the other thread, hmmm, forgot about that thread, anyway, yeah, I'd be ripping them apart pdq.
The RS2i is about as different from my Hifiman HE400i as vodka is from merlot. Both very good in their own settings, but not to be mixed together. The Grado is direct and clear, with every detail upfront and in your face. Detail is outstanding, bass is deep and impactful, but not at all overblown. The whole presentation is best described as clear. Soundstaging and imaging fall far short of the Hifiman though. And the Hifiman is much more lush and beautiful. Making everything fit in with the alcohol reference. Music you'd listen to while drinking vodka is perfect for the Grado, rock and roll, alternative, jazz fusion, etc all go with the Grado. Female vocalist, Celtic, softer jazz, classical all go best with merlot and the Hifiman. Nice to have the options.
