Direct: PM-11 $320
PM-11 is a rather simple but rather unusual 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 and very low noise, especially hum, as in the complete absence of it. The PM-11 comes with a socket type power supply, or upgrade to thr BPS for the best possible performance.
Harmonic Distortion (for 2V RMS at output): 0.1%
Input Impedance: 47k ohms
Input Interfaces: 1 group (RCA)
Output Interfaces: 1 group (RCA)
Grounding Interfaces: 1 group
Consumption: 1 watt
Dimensions: 60x 92x 130mm（HxWxD)
PS (The battery power supply with charger):
BPS uses NiMH batteries to provide DC24V output. It has an automatically activated charging function.
When the battery voltage drops to 20V，it will be charged automatically, still providing DC24V output through the power transformer, until the battery is full. The BPS will then disconnect the transformer and continue to use the battery.
