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.
Marten Parker trio-Diamond Edition are incredibly good speakers use very detailed ceramic composite drivers Marten uses only premium quality parts throughout ,the $$ Jorma internal cabling,WBT connectors,high  Quality Mundorf Xover parts  special Diamond Tweeter ,and custom feet and damped cabinet ,several Excellent reviews out there on them.
and these beat  speakers of much higher cost .
@ronboco You'd be making a wise choice with the Rockport Avior ii's and the 866.  I own Rockport Altair 2's and would never let them go.  There's something very musical about speakers Andy Payor designs.  And Rockport's build quality is world-class. I use a Gryphon Antileon EVO stereo amp.

I recently purchased a Boulder 866 for a 2nd home system I was planning.  I temporarily hooked up the 866 to my Altairs and was pleasantly surprised on the musicality and level of control the 866 has on the pair of 15" side firing woofers in the Altair's. Not many amps are able to manage those woofers. Boulder is likely conservative in their power rating of the 866.  There's no harshness from the Be tweeter and the bass management is very close to the Gryphon Antileon EVO.  I suspect the 866 will mate very well with the Avior ii's.

Good luck and enjoy the journey!
