Legend of Digital Audio continues......

CD Player was launched in 1982 by Philips Netherlands. Then Philips started the collaboration work with a pure HiFi expert team of Digital Audio in Japan, thus the reference CD Player series for Audiophiles was created. In this project, the expert team made the World First Stand-alone CD Transport and DAC unit, CD-12 (Philips LHH 1000), also the World First Bitstream Conversion CD Player, CD-11 (Philips LHH500).


Today, Soul Note inherits the DNA of that Philips reference CD Player series because that pure HiFi expert team is the one who made those Legend CD Player series with Philips, called CSR, Inc. Japan. CSR, Inc. Japan has come back to continue Legend story of Digital Audio !! And is using the very same facility of original Philips manufacturer.


Soul Note by CSR, Inc., it's a living Legend you can experience today !!
