Ayre KV-5 Twenty or Parasound JC 1

I’m using an Ayre KV-5 Twenty amp with a KX-5 Twenty preamp to drive KEF Reference 1s, but I have three JC-1s in cartons with the plan to sell them. I also have a JC-2 preamp. I’m loath to unbox the JC-1s just to try them with the Reference 1s, so I wonder if anyone has compared the two amps and can give advice. I use a QX-5 Twenty for Roon, so like the idea of an all Ayre setup, balanced of course, but it also would be balanced with the Parasound JC-2 and JC-1s. Any thoughts/advice?
