Personnely I have tried the Klipschorn with a Cary CAD2A3SE.
at maxi of 5 watts was a knock out.The best sound was using a Mac275 had very good bass extension.Mids and highs was very close to the SET 2A3.The Advangarde Uno was good on highs but the Mids/low end had a hole in the middle. I think it seems that the active bass end was not matched.
What ever you decide your ears are the final judgement but getting information narrows down your search for the best.
Have fun.
