I got my Q701s yesterday and my E10 today!!! I was glad to find that the bass is significantly better with the amp. So far I'm really happy with them except that they seem fatiguing and maybe too bright. Hopefully that will get better with break-in... unless it's just me with my sensitivity to high frequencies. Does anyone with a Mac have suggestions for: 1) Break-in software or mp3s that can be repeated and have some silence in to give the drivers a rest 2) What playback software you use. I'm thinking one that can take full control of the output, and has an equalizer. Is it common to take the frequency response curve for headphones and then EQ the computer's sound with its inverse, to aim for a flat response? Or at least to EQ-out peaks like we have at 2 and 7kHz? Or is it impossible to digitally EQ music without screwing it up somehow?
