Representing Rotel's best performance and released to celebrate the Japanese brand's sixtieth anniversary, the Diamond series collaborates with an integrated amplifier with a CD player/DAC. The first of these, the RA-6000, incorporates the technology of Rotel's top-of-the-range Michi models and offers an exciting combination of power, authority and clarity. The tuned DT-6000, meanwhile, doesn't just deliver improved CD playback, it's called a DAC transport for a reason, and has an excellent 384kHz/32-bit conversion stage that works well with other digital sources. When combined, the Rotel Diamond Series duo becomes an insightful, dynamic music system that will thrill and delight.
