Lector digital opto-laser rx-tx system
ST-II baionet hi-quality fiber glass

This system of connection in glass fiber optics  guarantees in absolute the best connection for the transfer of the digital signal among the CD-player transport and the DAC-convertor. 

In fact this system of connection allows to get these important results: 
-perfect galvanic isolation among the two apparatuses 
-important reduction of the transport of the jitter 
-connection to high speed with coherence of uniformity of signal 
-annulment of the electric effects of the copper cable

The perfect digital missing link between CD-Player transport and DAC-converter
