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!

Thank you for the recommendation. I will take a look and see if there is a Vandersteen dealer here in Colorado to go have a listen

Those are great looking speakers but unfortunately out of my budget. I’m looking at between 50-60 k ish.
