After doing various searches around here I have been leaning heavily towards purchasing the Grado Sr325i's. They seem to fit my taste in rock music. I mostly listen to prog rock and 70's rock bands such as Pink Floyd, Led Zeppelin and Porcupine Tree. Stuff like that really. However I also like to listen to jazz, house, orchestrated music, and more ambient music. I am really just wondering if these genres will be sounding decent on the Grado's. These headphones would be my first big audiophile purchase (coming from the relatively cheap Koss PortaPros) and I don't want to have buyers remorse after the purchase since they are so expensive. I plan on playing the music mostly through an Ipod touch (will be replaced later by a Cowon S9) and my laptop.
