Wow, to me, it's the GS-1000's rather than the RS-1's. I think they sound terrible compared to all of Grado's other headphones and aren't nearly worth their price tag.
I think the AT ATH-L3000 is the most overpriced headphone I've ever met. I remember hearing these at the northern NJ head-fi meet. I had just set up my rig and someone handed them to me and said, "I have the L3000's, want to try them?" I'm like, "I'm not familiar with those," and someone else said, "Do you have any idea how much those cost?" and I was like "nope". Having the understanding that the person had paid a lot for them, I put them on my head and was just immediately underwhelmed. How can a headphone that costs so much sound so blurry and confused? The sound was well-balanced, but jeez, the instrumental separation was just terrible.
