Expect the unexpected in retail, especially if it's a Hi-Fi shop. Some guy walked in once claiming he had blue Qualia's (not functional), so naturally I asked him to bring them. Sure enough he came back two days later with them!
We repaired it too, was just a short at the jack (thank god for him). They were huge on my head, apparently they're sold with either a S-M-L headband. He even brought it in its original packaging; almost as bad as Grado!
As for SQ, well, you'd best match it with a high end OTL tube amp; very strident and glary on most amps.
So now I wonder, what portable setup is that weekly visitor using to drive his Qualia.
