About The Rotel Diamond Series RA-6000 Stereo Amplifier
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, aptX 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 analogue 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.
Our Take
Rotel's new Diamond Series RA-6000 amplifier has quite the pedigree. This powerhouse of an amplifier owes its great sound to Rotel's 60-plus years of technical know-how and engineering prowess. Housed inside its all-metal chassis is a beefy amplifier section and an excellent digital-to-analogue converter that work together to take your music to new heights.
The RA-6000's Class AB amplifier is a testament to Rotel's passion for hi-fi. It uses a custom-made toroidal transformer to feed dedicated power to all the important circuits. The transformer is outfitted with high-quality capacitors that help it deliver ripple-free reserve power and current to every internal component. The company also physically and electrically isolated the sensitive amplifier circuits from any possible internal sources of interference to keep the noise floor and distortion low.
The amplifier can support up to four speakers total. There are two pairs of speaker wire terminals to work with, and convenient front-panel controls for switching between them or playing them both at the same time.
The RA-6000 has a killer digital section. A high-quality Texas Instruments digital-to-analogue converter chip takes care of the switchover from digital to analogue. The chip helps wipe away the digital "grime" from your music, giving you a clearer, more detailed sound across the board. The chip supports tracks up to 32-bit/384kHz and can even render MQA files.
You needn't rely just on physical connections for your digital tunes. This amplifier also has Bluetooth built in. Pairing your phone is straightforward and gives you a wire-free way to enjoy music from your smartphone or laptop. This amp can make the most of Bluetooth sources, too, since it supports high-quality aptX® HD streaming.
You'll find plenty of connections on this amplifier's rear panel. There are seven total digital inputs, including a Type-B USB for connecting a computer. There are also four analogue line-level inputs to work with, in the form of stereo unbalanced RCAs and balanced XLR connections. A dedicated phono input and built-in phono preamp let you hook up your favourite turntable and treat your records right. You can send signal to another amplifier and two subwoofers by using the amp's RCA preamp outputs.
There are also some control options onboard. There's a 3.5mm external remote input and an RS-232 input for using compatible devices to control the amp. You can even have the amp control external components thanks to its two 12-volt trigger outputs.
