The electronic design of R4 is far removed from the mainstream of compact systems available today where integrated modules are used for simplicity of design and cost. With best sound quality in mind we developed our own discrete technology Class A-B amplifier system and use select audio grade components in critical signal paths. This method is usually only found in high-fidelity audio separates.
For music and audio enthusiasts, CD is still one of the best ways to experience quality music and R4 features a multi-format player that will make your CD collection sound better than ever. Besides standard CDs, R4 also plays CD-Rs encoded with WAV, MP3, AAC or WMA music files and also displays track and artist information when this data is available on the disc.
