Hi, i purchased a Classic One II when i was in the middle of a upgrade fever, the speakers that i used with it are: Sonus Faber Signum, Totem Forest, Dynaudio Special 25, Magnepan 1.6, Klipsch Heressy and Reference 3A De capos. What started as a search for the best match ended up as a compromise because I had a financial set back but the Pathos always remained the no-trade player in my system. As you can see I used speakers of different character, technology and sensitivity and in every case i felt and my friends did too that the match with the Pathos was incredible. I was driving the 25s with Audio Research tubed separates and a Stratta III when I switched to the Pathos, the fullnes was such that i sold the subwoofer. I changed the 25s for a Magnepan 1.6 (big mistake), the guy the sold me the Magnepan was driving them with a big 400 watts Classe, he came over to help me set them up and he couldn`t believe that that was the Pathos driving his 1.6, i liked them far more with my Pathos, more detail and finesse and not lacking one bit of bass. With the Forest my experience was similar as with the 25s: Full sound, detailed( and smooth at the same time) highs, with the pathos i measured the Forest going down to 28HZ. With the De Capos, everybody was telling me that the way to go was SET tubes so i bought a Cary 300sei and it will be back for sale next week: The Pathos sounds more SET than the SET Cary, i never heard a SET amplifier and i was really curious about it but my Pathos is warmer, fuller and you can listen to the De Capos better at really low volume without missing a note(wich i understand is a forte of the SETs) In All i liked it better with the Dynaudios Special 25s( but then, the guy that bough my Dynaudios now wants to buy my De Capos) just because that`s my favorite speaker but it matched as well with all the speakers that i mentioned.
