Thought on Ayre K-5xeMP with PSAudio BHK 250

Does anyone have experience with these two items matched together?  I am looking into getting the PSAudio as a replacement/upgrade for my system and would have it paired to my Ayre Preamp.  Both seem to be well regarded but you never know how things will turn out when they are paired together and I would not have a chance to do an in-home demo.  Will need to commit to the BHK.  

Am patiently waiting for the new Revel Performa3 Beryllium line to come out to upgrade speakers but should have a similar sound proile to the Ultima Studios.
