Diamond Series RA-6000 Integrated Amplifier (silver)

The Rotel Diamond Series RA-6000 Integrated Amplifier celebrates 60-Years of heritage and tradition delivering performance, passion, and value synonymous with the brand’s iconic Japanese heritage. The RA-6000 supports an exceptional array of modern and legacy sources with RCA (3), XLR, Moving Magnet Phono stage for vinyl fans, aptXTM HD and AAC wireless Bluetooth, Coaxial (3), Optical (3), and asynchronous PC-USB inputs.

Conveniently packaged in the elegant Diamond Series industrial design the RA-6000 delivers 350 watts of robust, Class AB output power into 4 ohm speakers. An in-house manufactured toroidal transformer feeds dedicated power to all critical circuits utilising high efficiency, low ESR slit-foil smoothing capacitors delivering an abundance of ripple free, reserve power and current with exceptional control of rich, deep bass energy. Physical and electrical isolation techniques are utilised in the digital and high gain amplifier circuits reducing noise in the highly sensitive analog stages further lowering the noise floor and reducing distortion.

Digital sources are processed via a premium 32-bit/384kHz Texas Instruments Digital-Analog converter extracting the finest of details portrayed on an immersive sound stage. Coaxial and Optical inputs support 24-bit/192kHz PCM audio. The PC-USB input renders up to 32-bit/384kHz high resolution music files, unfolds and renders MQA and MQA Studio, and is fully certified Roon Tested for the highest compatibility with Roon software. Front panel controls, a back-lit IR remote control and 2-line display provide intuitive operation of the unit. Ethernet, RS232,12V trigger and external remote input ensure simplified integration with all popular control systems.
