Never owned a Unico, but last April-Sept '05 I owned a new Pathos Classic MKII for maybe 80 hours of play. Fantastic aesthetics, hard to match, and very pleased by the way it worked with my Cains and Shanling. Terry Cain suggested that running tubes with his Abbys would surprise me ... and he was totally correct. So, I replaced the Pathos with a tube amp. Nevertheless, the Pathos is nice amp, that's for sure.
