true reference top loading cd player
 

All solid state design

The  Alphatop signature is a top loading cd-player with separate power supply unit. 

This top loading cd player incorporates total new technology around hi-resolution digital to analog converter with upsampling by digital signal processor technique (DSP). The circuity uses a discrete device amplifier for output stage, this active device has been  selected at very low noise operation and tracking precision for both stereo channels at better than 0.1 db ! For best clear,detailed and smooth sound no one capacitors are in the signal path: the analog output is dc operation. A solid shielded cabinet (aluminium for aereonautic applications)  has tickness of  2.0 mm to reduce interference from emc field for a better signal to noise ratio.

 

Great attention by designer has been focused on design of  power supply, this circuitry operates with over four-thousand microfarad capacitors for reduce  noise and best reservoir energy, this hi value capacitors works together with  special ultra low noise voltage regulator devices as shunt-parallel technology.
