I have Wavelength Cardinal Signature XS's. (Wavelength 45's silver, also). I have never had an opportunity to hear "Franks" yet, nor any other 300B amp (or 45) before my purchases of them. Franks, Cardinal, Triton are all good choices, given appropriate speaker matings. Such difficult choices in life... :)
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!
