Any comments on the Quicksilver Horn-monos

I am considering these amps. and would like some user comments and or comparisons to either the mini mite or mid monos. Reference 3a MMDecapos and Supratek Chardonnay preamp.

I have owned a pair for more than a year. I use them with a pair of Klipschorn corner horns. These are terrific amps. Dead quiet. Effortless presentation.
