The Diamond Series combines 350 watts, high-resolution DAC and comprehensive control
Rotel RA-6000 is a Class AB integrated amplifier rated at 200 W per channel into 8 ohms and 350 W into 4 ohms, with 32-bit/384 kHz DAC, XLR, PC-USB and MM phono.
The Diamond Series model combines a high-current output stage with a complete digital platform and analogue connectivity suited to high-level systems. The in-house toroidal transformer and slit-foil capacitors support dynamic delivery, while PC-USB, MQA, Bluetooth, Roon Tested and balanced inputs allow many sources to be concentrated in the same integrated amplifier.

Power and control
RA-6000 delivers 200 W per channel into 8 ohms and 350 W into 4 ohms. A damping factor of 600 highlights attention to load control, while declared THD remains below 0.0075%, combining high current and linearity in a single Class AB output stage.
Diamond power supply
The large toroidal transformer is manufactured in-house by Rotel and works with selected reservoir capacitors. The supply section provides current to the output stage with substantial headroom and helps keep voltage stable during the most dynamic musical passages.
DAC and digital sources
The digital section uses a premium DAC capable of operating up to 32-bit/384 kHz. PC-USB, coaxial and optical inputs connect computers, streamers and players while keeping conversion inside the amplifier, and MQA/MQA Studio extend compatibility with encoded files.
Analogue inputs and XLR
RA-6000 provides RCA and balanced XLR inputs for high-level analogue sources. XLR offers a differential connection that is particularly useful with longer cable runs, while RCA maintains compatibility with the great majority of traditional Hi-Fi components.
MM phono
The dedicated phono stage allows direct connection of a turntable with a moving-magnet cartridge. Vinyl therefore enters the same preamplification and volume-control chain as the other sources without requiring an external phono component when the cartridge is compatible.
Bluetooth and Roon
Bluetooth supports aptX™ HD and AAC for wireless listening from compatible devices, while Roon Tested certification verifies the amplifier within a Roon system. These functions complement, rather than replace, the wired connections dedicated to the main sources.
Control and integration
Ethernet, RS232 and a 12 V trigger facilitate installation in automated systems or technical racks. A and B loudspeaker outputs can manage two pairs, while the two-line display and backlit remote keep functions accessible without relying on a software interface.
Chassis and dimensions
The chassis measures 431 x 144 x 425 mm and weighs 18.81 kg. Diamond Series construction separates the power supply, digital section and analogue signal path.
