Teleshack and Georgemg. What dissapoints you more specific?
I did not like old "in house SF sound".
I heard it briefly, but i remember an older man, he had the AA and he did not like them either. I did find, in that demo we where at, a very good depth and very tight bass. Not any bloom or warmth. But it was smooth and very revealing. The soundstage unfolded with a laidback perspective.
Seemed to suit all genres instead of biased (if i may put it like that;-)
