I would get Grado SR225, $100 more but much better, this is Grado's best value, after that you jump straight to $700 RS-1. Yeah, headphone amp too, there are some for about $100.
Yeah, I've been using Grado 225 for a few years, mostly with computer. I had 80 before and I heard 60. I am also very familiar with RS -1. Wanted to upgrade to them but spent the audiophile money on something else. But I'll get them.
Jusk make sure you know that Grados have no isolation whatsoever. You need to listen in a quiet room, just like with your speakers. I have a pair of G1000i and they're great.
