CD 1500 Player

The analogue stage plays a vital role in high performance of the Oracle CD player , it filters the quantification residues , it eliminates left over pollution from the supplies in a common mode and the electrical rejections of the different internal circuitry of the CD engine drive board.The fine tuning of our digital to analogue converter board has resulted from a 3 years intensive research program before reaching our goal. The goal was to eliminate the need for, and use of internal pre-amplification circuitry needless to say we succeeded.

Digital to Analogue Converter Board Workload Specifications Balanced input
