I have been enjoying the beta release of the new K&K Audio 3 stage, fully differential, transformer (Lundahl amorphous of coarse) coupled phono pre now for several months. In every way it out performs the SE version. Dynamics, sound staging, flow, pace, transparency, natural timbres, etc. I haven't heard anything better. At Kevin's suggestion, I recently replaced all grid-stopper resisters with smaller value 10 ohm Audio Notes. Nice improvement. Music is even more incisive with better dynamics. I've been so impressed with it that I've rebuilt my line stage with the same circuit as stage 3 of this phono pre. When the retail version of this unit becomes available they will be pricey ( all that Lundahl iron, 2) LL1931 MCs, 2) ITs and 2) line out , plus large PS trannie and choke ), but well worth checking out.
