Agreed the PM-17 MkII is something special.
One of the few amps I regret selling.
(I'm sure the KI is a little bit better - by how much I don't know.)
The PM-10 will probably retail for 140k or so.
In that price range there are many very, very good options to consider.
Audio Research, VA Black Widows, Accuphase, Devialet, Chord, Classe, Perreaux, to name but a few.
