Jolida JD-9A. List price $450. Nice big power supply (unlike the wall warts of all the lower cost phono preamps) and tubed buffer stage. Highly configurable for gain, output, capacitance and resistance. Also easy to modify to improve the sound further by upgrading the power cord and putting in better tubes, op amps, and/or capacitors.
I upgraded from a Cambridge 640P about a year ago. I swapped in better tubes, power cord, and Vibrapod isolators. I'm ver happy with the sound--smooth, detailed, linear, no hint of midrange glare, better dynamics.
