First of all, congrats on the Nagra Classic Amp. I've heard it once and was amazed by its pure performance and amazing bandwidth. Even at very loud levels with the orange clipping light activating, it never lost its composure, not one bit.
I've never heard the Paradigm Persona 3F or the Kef Reference 3 (would like to) but I have heard the Focal Sopra 2, many times in fact. I've never heard that speaker sound good but for one time. And that was with PrimaLuna and Audio Research tubes. I still find that speaker to be quite clinical and not to my liking.
Back to your Nagra. I heard it about a month ago in stereo mode with the matching Classic Pre. Source was dCS Debussy DAC with Network bridge and AudioQuest cabling. Speakers were the fabulous Wilson Audio Sabrina's. It was really really good. It may be my favorite pairing of the Sabrina's that I've heard. I can tell you first hand that this is a very well matched system and so I know the Sabrina's work very well with Nagra. Dave Wilson indicates that he uses Nagra in a video I saw on the tube. Search Youtube for Wilson and The Audio Salon in Santa Monica for a video of Dave talking on Nagra. The owner of The Audio Salon, Maier Shadi, is a true gentlemen and could help you in your search. I only know Maier in that he demo'd that system for myself and a friend. I have no other connection with him but can highly recommend him.
