I'm actually glad that you found the RS-1s and PS500s to be that different, cause I would like to add the RS-1s to my little collection still. I'd rather they have different sound sigs as opposed to beign more similar.
congrats on the 500s...I'm sure you've probably see me say plenty of times that they're my favorite headphone...and it's hard for me to imagine that changing anytime soon, although the PS1ks are still out there waiting for me lol.
Thanks! I believe you. I did try the PS1000 there for the second time today , since I have few Grado sound signatures in my memory now, that one is AWESOME! It just too big for my head and wallet...
