Recommendation on power amp


I would like recommendations for a power amp for my system which comprises of 
theta digital gen viii series 3 preamp/dac, ayre cx-5xe mp CD player, LUMIN mini u1 streamer, kef blade 2 with a pair of jl audio f113v2 connected with a jl audio cr-1 active crossover, kimber cables , rega rp8 turntable , parasound jc-3 phono stage.
currently using a pair of parasound jc-1 . Thinking of ayre mx-r twenty . Would like recommendations on compatibility of the ayre with the above system .
thanks everyone in advance .

It's always great when you can audition an amp with your speakers.  What amps does your KEF dealer sell?   When I bought my speakers I was able to listen to them with my amps and pre.... Owning the KEFs already you have a benchmark how they sound with excellent amps.   Obviously everything including the room plays into it.    Gonna be tough, the JC 1 amps are very good.  Good luck on your search.  Theta has some nice offerings that might pair nicely with your pre.
Thank you for your response . The theta dealer is recommending the Prometheus monoblocks. I was not very excited with the pairing . I am looking for a warmer sound. My local ayre dealer would not do a home demo for me . The mx-r twenty sound good in his showroom . My local kef dealer does not have ayre. 
Actually oddf not tough at all we had Jc1- on our Blades the $14k Elecrocompaniets were better so were the Chord mono blocks which were about $14k also 

Jc 1 are good amps for their price and power not as good as $20k amps.
