Ovo je KI verzija tog nekada vrlo cenjenog cd playera. To je bio jedan od prvih upgrade-a Ken Ishiwate, koji su kasnije postali poznati, cenjeni i priznati. On je koliko se secam radio unapredjenja svojih uredjaja a da nije menjao osnovni design: bakarno kuciste uredjaja, dodatno dampiranje kucista, bolji kondenzatori, ... sve ono sto danas gotovo svaki DIY-er obavezno radi (sa izuzetkom bakarnog kucista).

Bilo bi interesantno uporediti ovu masinu sa nekim danasnjim cd playerima i videti kako se drzi .... Koji bese DAC cip unutra ? TDA 1543 ?

This DAC Chip is very well designed. While it combines a crystal-oscillator, a digital interpolation filter (8 times Oversampling) and two Delta-Sigma DAC's on one Chip, all these components have separated power-supply and ground connections run out from the chip.
