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!

Try my setup, which at the moment I feel (who knows how I will feel in a year, assuming I still have a pulse) is 98% there:

You can use the $30K you save to buy the wife a little Mazda Miata sports car. Then she will speed off to her favorite high fashion clothing store, and leave you alone with your hobby.

AND … you will still have about $5K left over to waste on overpriced cable. Doesn’t get sweeter than that, imho.
OP, @ ghasley expressed his displeasure at members recommending something they have never tried, and I fully agree. I also do not think you will get an unbiased opinion from retailers.

What I am recommending, without hearing, is the speaker cable from Silversmith. He looks at the whole process differently/correctly. I include a link to an interesting review and hope you find it valuable. At their price I am very tempted to try.

Heard the Roger Sanders speakers and amps while back, was one of the best I’ve ever heard.
bass, mids, highs, all near perfect. 
Those Magtech amps are something special!

  Sanders sound!
My current end game combo is Aurelic Vega DAC + Gryphon Diablo 300 + Dynaudio C4
