Rotel RA-6000 Diamond Series Integrated Amplifier

Recommended Component 2024 – Stereophile

Passion, Performance, and Power

The Rotel Diamond Series RA-6000 Integrated Amplifier celebrates 60-years of Rotel 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 a wide range of inputs. These include stereo RCA (x 3), XLR, Moving Magnet phono stage for vinyl fans, aptX™ HD and AAC wireless Bluetooth, Coaxial (x 3), Optical (x 3), and asynchronous PC-USB inputs.

"Recommended Component" Honors

Stereophile honored the RA-6000 by awarding it the magazine's coveted Recommend Component status for 2024.

According to Stereophile,"The RA-6000 let recordings sound like themselves, open and clear with no issues to distract listeners. 'It was a joy,' [John Atkinson] wrote, adding that in his system, 'the RA-6000 played LPs even better than CDs—and that's saying a lot.'"

"One of the Best"

"The Rotel RA-6000 absolutely deserves to be considered one of the best integrated amplifier-DACs… [at its] price point," notes Roger Kanno, SoundStage! Hi-Fi, February 1, 2023. "It offers a ton of performance and flexibility for the money. This new Diamond Series RA-6000 really takes Rotel’s classic amplification products to the next level of performance; updated, but still maintaining their familiar, classic look, and coming in at a price below that of Rotel’s highly regarded Michi products."

Big, Robust Power

The RA-6000 delivers more than enough power to fill large spaces with beautiful music. Conveniently packaged in casework graced with 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 utilizing 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.

Low-Noise Performance

The RA-6000 features low-noise circuitry so that you hear the music rather than interference that can muddy sound quality. Physical and electrical isolation techniques are utilized in the digital and high gain amplifier circuits, reducing noise in the highly sensitive analog stages further lowering the noise floor and reducing distortion.

Catering to Digital Sources

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.

Convenience Features

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.

The RA-6000 is available in your choice of a black or silver finish.

"The Rotel RA-6000 absolutely deserves to be considered one of the best integrated amplifier-DACs around the $5k price point. It may lack a couple of features, the most notable being a room-correction system, but if you don’t want or don’t need room correction, it offers a ton of performance and flexibility for the money. This new Diamond Series RA-6000 really takes Rotel’s classic amplification products to the next level of performance; updated, but still maintaining their familiar, classic look, and coming in at a price below that of Rotel’s highly regarded Michi products."
