RCD2.2 linear Nos Tube CD-player

The appeal of non-overampling DACs lies in the less is more audio ideal, the fewer components there are in the
signal path the more of the signal should get through. The NOS DAC was conceived by Ryohei Kusunoki in 1996. He wanted to find a way of avoiding time smear in digital audio and, therefore, considered the digital filter to be the biggest cause of this problem. As it's the digital filter that does the over oversampling, he built a DAC that did away it altogether and used an analogue filter after the DAC.

Linear technology (applied to CDplayer):
-Non-oversampling, no digital filter
-Passive I/V conversion In progression
-Short pass length, less number of parts
