The Reference Phono 10 is a sonic blockbuster that establishes a new standard in analog music playback. Great vinyl takes on an explosive, dynamic quality that is normally encountered only in a live performance, whether the crescendo of an orchestra, a roaring rock band, or the intricacies of a solo piano. When called for, the stage is vast, holographic, enveloping: Dimensionality is redefined, with an engaging, ‘reach out and touch it’ quality. The RP10 resolves so much detail without grain, delighting listeners with new information extracted from those familiar grooves.
