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!

Silversmith Fidelium speakers. $1200 an 8’ pair and $175 for the unique and excellent bi-wire. They made my $6000 cables sound like junk. It is said that the Fideliums can go against any regardless of price.

I have heard good things about the silversmith cables and will definitely check them out. Thank you 
If I'm reading between the lines correctly, I thought it interesting that in the recent Stereophile review of the Boulder, the reviewer found that it did not best the Krell integrated he used as comparison, just that the Krell was slightly warmer and the Boulder more neutral.
