Anyone pair up the SA6s with a decent amp? I really can't say the Minibox adds much to the SQ, at least not with the Zune HP out or the Sony HP out. With the 716s, an amp is required, for both headroom and SQ. Not so with the SA6s, at least not that I can tell. I'd be interested in anyone who has tried using an amp with them.
Five hours of listening, and so far, no flaws on the SQ front. I did add a small tweak, but I am a shirt clip fan. I had a clip sitting around, so I attached it right below the Y joint, and it makes a major difference in terms of the wires swinging around. Nothing new, but I always find shirt clips to be mandatory with my portable phones (imagine clipping the Grado SR80 cable to your shirt?).
