My two cent: The HD600 sounds gorgeous with the Projet Polaris, i get all the benefit of a solid state amp, with the harmonics distorsion of the JFET that mimics the tubes. Wide soundstage, precise and smooth. I'm not even sure if the crack would sound better.
I never heard it before. I like the JFET stage, but I didn't like that it was a push-pull amplifier and a class ab amp. Push/pull cancels out even order harmonics and sums the odd order harmonics, if it was only push/pull after the JFET stage it could work better though (not sure what method was used). Push-Pull can also run into phase issues if the push and pull parts get miss-matched even slightly. Single ended is just much easier to implement, though it wastes more power and has a higher noise floor though I'd rather have that than odd order harmonics from push-pull stage.
I would probably like project horizon III more for instance since it's a Class A OTL amp. I would need to audition both though.
Garage 1217 needs to make a JFET Class A, single ended, solid state amp, but some amps do that already (Asgard 2).
