LO-D Power-Pre combination is unique, it uses Power mosfet transistors for output stage,
Thus provide best possible low noise/Linear characteristic for audio amplification.
Excellent sound quality and enough power to run 10-15 inch speakers.
 
Audio circuitry is simple thanks to mosfet ,which are voltage driven,Therefor not requires complicated circuitry.
 
This is 100V only
Technical spec. of HMA-4500
Techncial spec. of HCA-4500
