Ok, so I tried the DT990s. To me they sounded fantastic. Like I previously mentioned, I have nothing to compare them too so I didn't buy them right off. I listened to Spotify via an external amp. I tested tracks from, Dire Straits, Norah Jones, YES, James Blake, System of a Down, Damien Rice, Frank Zappa.....So a good range of music. The only thing I kind of didn't like was how forward Norah Jones' vocals sounded. MIght have been the recording though, or that the phones were new out of the box. Either way, I really enjoyed them. But again, I'm not really going to be listening to that much digital music through them, so I guess it's hard to say how different they would sound when listening to vinyl. I've been reading extensively on the Grado appreciation thread, but up to page 150 I haven't come across anyone who has mentioned the sound of the Grado's whilst listening to vinyl. I know the sound is going to vary drastically depending on the rest of the equipment, but still.....I think I'm going to go for the SR80e and if I don't like them, I can always sell them on for a small loss.
