I respect your fidelity to the Qs. I share your sentiment despite that I am now listening to my K7XXs that arrived yesterday (which are putatively K712s in black). I am loving these so far but know that the Qs have their own unique signature to offer, which is why I shall happily keep them.
I'm curious how your K712s are K7XXs. Have they been modded somehow, or are you referring to the similarities in the K7XX/Q701 drivers? Or are they not K712s?
