I'm enjoying a second hand Audio Research LP1 that I think is very satisfying. Would be interested in others perspectives on this.
"The LP1 has 47dB of gain, perfect for higher output (>1.0mV) MM and MC cartridges. It is a hybrid design utilizing one 6H30 tube, special low noise JFETs, custom Audio Research designed power transformer (made in the U.S.), and multiple stages of regulation. There is no overall feedback, and it is noninverting. Inputs and outputs are single-ended."
