I just bought a Audio Technical M50, it's quite different from the HD515 I have had for a while.
The M50 seem to have more clear highs, but the sound is not as natural as the Sennheiser HD515..but the 515 doesn't have crystal clear highs like the M50
Would I hear much difference if I upgrade to HD558 instead? would the high's sound better than the HD515.. I seem to read somewhere the 518, 558, 598 all have similar frequency response..
Sennheiser has better sound stage,but the M50 seem to have more clear sound. I can more more detail with the M50, but sometimes feel like I'm hearing too much detail and it's very sensitive to the source of music I'm listening to, with lwo quality mp3 it sounds worse than the HD515
