Recommendations and thoughts for end game speakers and amps


Good morning all. I am looking at Rockport Avior ii speakers. My dealer likes Boulder amps with these but I wanted to get everyone’s opinion first. I will be getting an integrated with HT bypass. Right now I’m looking at the Boulder 866, Gryphon Diablo 300, and the Simaudio 700iv2. Has anyone listened to these speakers with these amps? I’m looking for highly detailed but not harsh highs and mids and outstanding bass as well. Basically a set up that performs fantastic from top to bottom. If you have any other speaker or amp suggestions please let me know. Thank you!

I know Andy Payor is fond of Gryphon amps so hard to see going wrong there.  Another one that’d probably sound great is Vitus — here’s a nice one at a good price...

Best of luck.

Thank you. I’ve been reading good things on the Vitus amps here and will check them out as well.

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.
