I have owned the Franks Mk II for a couple of years now, and I also matched them for a while with the Hovland (a great preamp) until I finally got few months ago the CSL preamp, which is first class. For me the Franks are the best SET amps I know... but, of course, I don´t know all of them (but I have been around audio for 40 years). What I like of the Franks is something simple: they reproduce live sound (or at least that is what I feel when I listen to them). Not the last world in low bass, of course, but everything else is beyond good.
Any expereince with Coincident Frankenstein II Amp
Currently driving Coincident Super Victory speakers with the Topaz Wyetech amp and the results are amazing. I had heard that the Frankenstein II full chrome version is best in class for my speakers and Hovland pre. Any expereince with these amps and or feedback is welcome!
