the kinki ex-m1 is less of a risk, just got mine today, i'll be doing a review.
i have a $2.8k unison research nuovo integrated that's going up for sale now.
demoed one today. the revo. digital performance was decent. my concern is the manufacturers grip on a service model to align with distribution. 
Have been thinking about the Norma Revo ipa-140 for my system for a while, but not being able to have a Home demo makes the outlay a bit risky, the amp gets very good reviews in Scandinavia and Europe.
