Well, I'm back in the Grado fold after being out for about a year or so. I've owned pretty much every Grado out there over the years, but missed having one in the stable. I picked up a pair of PS500s and I'm very happy with them. They are very similar to my (now sold) HF-2s, but with a wee bit more mid-bass and wider sound staging. Actually of all the on-ear Grados (RS1i included), the PS500s have the widest soundstage out there. I think I'm gonna pick up a pair of the bagel pads tomorrow and see how they sound.
Anyhoo, listening to some Kid Rock now with the PS500s and yessir, Grados just rock!
Wow nice to hear from you again being back to grado. Please post your most detailed review of PS500 because i'm looking forward to buying it.
