I know the Q701 have an impedance of only 62 ohms, but the normal gain setting on the STX just doesn't cut it for me. I can crank the volume to 100% and it still sounds a bit weak. On the high gain setting, 30% is uncomfortable loud. Is it just a bad amp match? I didn't have this problem with the Fiio E9, which from what I've read is about equivalent to the STX amp. 
 
Sennheiser HD 598 gets uncomfortably loud around 50% volume normal gain, and ATH M50 doesn't go above 33% volume without being too loud. Just thought I'd include that information. 
 
Will using the High Gain setting damage the headphones, or cause any sort of distortion?

No, it only adds 12dB of volume. It's hard to kill headphones with anything you would be able to listen to.

how about using the EXTRA HIGH GAIN ? 300-600 OHMS ? will it damage the Q701 ?

No.

will i benefit better sounding with it ? i think the bass improve with the EXTRA HIGH GAIN on the Q701 and STX.. but was just wondering if on the long term i am damaging the headphone or messing up its dynamic range (considering i am lowering the volume for a normal listening vol)
