The RS-1's were mindblowing for classical. I was talking to a head-fier recently, I think it was Ebonyks, and he commented on the fact that although he enjoys going to classical concerts he doesn't own one classical CD. I thought about this, and realized it was quite the same for me. I think the reason is that my system really isn't up to reproducing what a real orchestra sounds like, and when I'm sitting at home I don't really ever feel like putting on a classical CD. I don't even own that many though I like classical music a lot.
With the RS-1's, all I was listening to was classical. You have to know me to know that I never do that. To use my dad's words when I let him try the RS-1's on, "it's like a mini-orchestra in your head." I was right there with the performance. For the first time classical sounded right with my system, so I was listening to it. I'll note that this didn't happen when I owned the HD580, rather that sat in a drawer for a couple months before I sold it. Okay, maybe that sounds a bit harsh, but it's the truth.
Back on track, I wonder why people complain about comfort as well powerdog. I've never had a problem with Grado comfort, and thought the RS-1's were very light and comfy.
Anyway, I can't wait to one day own RS-1's and I wholeheartedly recommend them.
