Audio Research Reference 6. I have owned previous lower en ARC preamps, Reference 5SE (6 years)… and for the last couple years Reference 6SE. I can’t recommend it too much. For nearly forty years I paired these with Pass solid state amps.
My journey to real musical enjoyment started with an ARC phono stage and culminated in all ARC gear. You can see it in my profile. I used to owned some Sim Moon equipment, it is very nice, but you are not going to get the natural musical sound out of it you will ARC.
