Plenty of power, tiny footprint, looks decently built. Sound is the warm side of neutral. Powers the HE-400 to a level too loud for me to listen with no detectable distortion. Quality improvement of the HE-400 is sadly not there. However, it does seem to improve the X2. Gets them to open up. Better details, tightens the bass, mids still as stellar as always. Similar to my JDS Labs cMoy but with TONS more power (even on low gain) but with less warmth which the X2 doesn't really need additional warmth from an amp anyways. So the amp is a winner I think but the HE-400 is not. I'll listen to some more stuff with them to get a better idea but at this point I'm 99.9% sure the HE-400 is going back and the X2's have found a new home.
