I recently picked up some AKG q701's to replace my AD-700's. I liked the AD-700, but they had issues i didn't like (such as siblance, unnatural sounding highs, and an annoying lack of lows). The minute I put the AKG's on my head it sounded perfect, everything was tonally accurate and linear (my preference of sound). I have listened to them for a good two weeks now every day for several hours and i really can't think of anything i don't like about the way they sound. Everything just sounds perfect, with every album i own, every videogame i've played, and........even movies sound great (i usually cannot stand watching movies with headphones, they always sounded unnatural).
Unless you guys can recommend something that is even more tonally accurate, there is no where to go in terms of upgrading. Is there anything out there?
