I recently moved up to Rockport Avior IIs and a Gryphon Diablo 300. It is an excellent combination, as the Aviors like an amp that can deliver lots of current. Both the Aviors and the Diablo are excellent throughout the frequency range with no real weak spots. I’ve listened to other speakers in this price range (Wilson’s) which were excellent, but I felt they still had some weak spots compared to the Aviors. The Wilson’s had a bit more detail, but also had some additional harshness, to my ears at least. But that’s really a personal preference, YMMV. One note, the Aviors are wired internally with Transparent Reference cable, and when they are sent out for review, Rockport requests that the reviewer use Transparent Reference cables for at least part of the review (see the Stereophile review). Because of that, I tried out those cables and end up going with them. Good luck!
