Hello guys. I'm looking to upgrade from my first set of audiophile cans (Grado SR60i) and I'm not sure what to get. I like the sound of the Grados, but I don't have much to compare them to. While I want good accurate sound, I wouldn't mind if my new pair had a little more low-end punch than the Grados. Other than that, I am looking for a good soundstage, good separation, and as much clarity as possible. Open or closed does not matter. Comfort is also a big deal to me, which is why I think I'm probably looking for full-size headphones. Unfortunately, I don't think there's anywhere in my area where I can go listen to higher-end phones, so I am coming to you guys. I've been looking at the Sennheiser 555, 558, 595, and 518s, but I'm really open to anything. I'm looking to spend $100-200.
