Hello
I have tried the Gryphon Callisto and owned the Sonata Allegro Preamplifier, also I owned most FM acoustics products. The best audio gear on the planet is Kinoshita/Rey audio gear. www.Reyaudio.com This stuff is hand built by genious Shozo kinoshita. I now own his MSP-1 and HSQ4200 amplifiers. There is no better.
