Regarding your question about listening to the Aviors with other amps - I originally was using a Levinson 585 with the Aviors. On my previous speakers (Focal Kanta 2s) it was fine. However, it had some weaknesses that the Rockports revealed. Some thinness and lack of detail in the upper midrange and a lack of slam in the bass, in particular. The Gryphon, however, sounds spectacular with the Aviors.
