Music Reference RM4 Tube Preamp
The RM-4's job is a specific and critical one: take the hair-thin signal from a low-output moving coil cartridge and raise it cleanly to moving magnet levels before it hits your phono stage. 30dB of gain, adjustable via resistor plugs. Cartridge loading, same way — you dial it in for your specific cartridge rather than accepting a compromise. Two 6DJ8 tubes do the work, and a relay-controlled power-on delay holds the signal for over two minutes until everything is properly stabilized. That's not a quirk — that's a designer who understood what mattered.
The result is exactly what it should be: dead quiet, musically transparent, and out of the way. No house sound, no coloration, just the signal your cartridge is trying to tell you about.
No Box or Accessories.
