The Sutherland N1 preamplifier is the pinnacle of a full function preamplifier. They occasionally appear on the used market. As its name implies: "all-in-one."
Best Full-Function Preamplifier
Consulting the collective wisdom on the best preamp with built in phonostage (MM/MC). DAC not required but OK if it has one. Below $20K retail. Must be a no compromise solution--outstanding linestage and a flexible, great sounding phonostage that would not make you wish you had separates. Thoughts?
