The Diamond Series, showcasing Rotel's best performance and released to celebrate the Japanese brand's sixtieth anniversary, features an integrated amplifier/CD player/DAC. The first of these, the RA-6000, incorporates technology from Rotel's high-end Michi models and offers a thrilling combination of power, authority and clarity. Meanwhile, the matched DT-6000 not only delivers enhanced CD playback - it's not called a DAC transport for nothing, and features a superb 384kHz/32-bit conversion stage that can be used perfectly with other digital sources. Combined, the Rotel Diamond Series duo becomes an insightful, dynamic music system that will thrill and delight.
