pass labs compatible with kef reference 203/2

Are pass labs xa100.5 power amp and xp20 preamp compatible with key reference 203/2?
My experience is limted to a brief demo at a dealer, but the 205/2 with a Pass amp and preamp (not sure which) filled a large room with very good sound on a variety of material. My guess would be yes, they are compatible.
Hi Bondmanp,
I submitted a reply a day or two ago that never showed. Try again; thanks for the reply. I agree with you; just don't see the Pass/KEF combon not sounding good but just wanted to get some opinions from those with experience. Thanks again!
