 Reference 40:The Flagship Phono Stage using NOS tubes to MM and then a quality  Amorphous core MC step-up transformer and a point-to-point wiring with layout for the lowest noise.  External power supply on an umbilical to lower noise. Quite stunning performance and very low noise for a stunningly large soundstage and exquisite detail.  90% of Phono sales.
$1,295

PM-13:The MM phono stage of the PM-13 and the PM-11 is the same, two single stage JFET gain stages with a passive RIAA equalization stage between them, and no negative feedback. The PM-13 adds an Amorphous core step-up transformer Moving Coil Pre-Preamp. It is very low noise and is suitable for most low-output MC cartridge. 

 

BPS: The upgrade power supply is the battery (with charger).  Thr PM-13 runs purely to the battery, which automatically charges when needed or the unit is turned off. 

PM-13 $520.  BPS $450

PM-11: is a rather simple but for sure peculiar, solid state phono stage with two different power supply options: battery (with charger) or normal. The idea comes from the tube circuit design. Two single stage JFET gain stages with a passive RIAA equalization stage between them and no negative feedback with very low noise, especially hum, as in the complete absence of it.
