Headphoneus Supremus
When I first got my X2s >6 yrs ago, I didn't yet own a dedicated desktop DAC or amplifier. I paired them with my then-new FiiO E10K portable, a modest but good sounding all-in-one. The X2's sound was great...loved it.
Six months later I had my first DAC and first real headphone amp. Forget what the DAC was; the amp was the single-ended Lake People G109-A. I couldn't believe how much better the X2s sounded. My first experience of scaling w/better sources, also the fact that volume is not the same as full sonic quality.
So yes, the X2s are very sensitive and can get up to a pretty good volume readily with low-power sources. But it's also true that having a better, stronger device supply the power will make an audible difference.
