Recommendations and thoughts for end game speakers and amps

@mglik 

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!

Retailers by definition sell the brands they carry.  The advantage is you can hear the combination.  The problem with this “hobby” is without the benefit of brick and mortar stores, we can go through this crazy ritual of flipping equipment just to find the right synergy.   My experience is that speaker/amp matching/optimization becomes more difficult they higher up the chain you go.  It’s took me 5 amps to find something that really made my YG Acoustic Carmels sing.   Took me 4 amps to find the same thing with my TAD CR-1s.   So I suggest go that is you like the sound of the Boulders with the Rockports, go for it…..   Hearing what yo hear beats all the opinions you’ll hear on this forum (an amp in hand is worth two opinions in the bush)
