Just by looking at reviews, i think i may go for the Audio Technica ATH-M50. The reviews are outstanding, does anyone have any experience with these headphones?
I have these, k701s, and Senn hd580s. My favs are the k701s, but I use them with a Heed Canamp and I am not sure how they will sound with the amp you mentioned. I don't like them as much with some of the other amps I own.
The ATH M50s sound good even without an amp and blocks out a lot of external sound, so they get a lot of use. The aren't as accurate or as open sounding as the k701s, but I still like them a lot.
My last choice of the group would be the Senns, but I like the ear pads a bit better than the pleather on the m50s, so they are more comfortable for long periods.
AKG also makes the Ad700 which have a huge soundstage but the bass suffers because of it. They are huge, but are very comfortable. They have a similar sound to the k701s (although they are not as accurate), but are a lot less expensive. They aren't as power hungry as the k701s, so they are a bit more flexible if you are on a budget. I use mine with a Little Dot MKIII amp that gives the bass a bit more presence.
Personally, if I needed a good all arounder on a budget, I would get the M50s.
