Replace Ayre gear & kEF Reference 1s with KEF LS60s?

How sensitive is your hearing at 87? It might not matter a whole lot other than the impressive rack of Ayre gear showing a level of success the ls 60 won't convey. 

Simplification sounds good. I have the QB-7(?) Twenty DAC. It is a great DAC. I get the appeal. However, if I was thinking that way, I would go the Linn DSM route. You can get the whole stack in one small box… and the performance is astounding. I have listened to various combinations. But it can have a streamer, DAC at several levels of cost/performance, preamp, phonostage and amp. I would have laughed at the idea ten years ago. 
 

I had the streamer / mid-level DAC in my system last week… and its sound quality was worthy of its price. One elegant little box. 

I had the top of the line Ayre DAC a few years ago. I replaced it with a Mojo Audio DAC which blew away the Ayre. 

FYI, after two days of debilitation from an unknown cause, I've decided to proceed with the plan outlined in my OP.  I plan to list the Ayre gear, KEF Reference 1s, and Salamander rack at AudioMart once I learn how to do it.  When enough gear is sold to cover the cost of a used LS60, I'll be a buyer.  In addition to the Ayre gear, I'll be selling 3 Parasound JC 1s and a KEF Reference 204/2C center speaker.  Then there a boxes of gear in the garage I should sell.

I listened today via Roon to the Ayre gear and KEF Reference 1s.  The sound is so good I've decided to keep that setup and sell other gear to cover the cost of LS60.  It comes down to a 3-tier rack of Ayre gear and two speakers or a 1-tier rack with Ayre disc player and two LS60 units, not much difference re simplification.  I will compare the sound of the two setups, keep one and sell the other, or perhaps keep both and replace the LS50 W2 with the LS60.
