The Audio Research Reference Phono 10 embodies everything we know about phono playback, and incorporates many of the insights gained in the development of the Reference Anniversary and Reference 10 line-stage preamplifiers. The Audio Research Reference Phono 10 is a true dual-mono design with totally separate signal paths for each channel, from the dual-mono power supply forward. There are separate high- and low-voltage transformers for each channel, and sufficient energy storage for a serious amplifier, fully twice the capacity of a Reference Phono 2, providing incredible dynamic headroom. There are twenty stages of electronic regulation, with separate vacuum-tube regulation for each channel. Dual umbilical cords connect between the power supply and the separate analog stage. The power cord inlet contains a 20A IEC connector. The dual-mono audio circuits are fully discrete, pure Class-A, with zero feedback. The low gain audio section uses eight 6H30 tubes, four per channel. Rather than using a step-up transformer, special high-gain, extremely low-noise FETs are used in the high- gain section. This approach is costlier than using a transformer, but it is well worth the dramatic performance increase. The design is fully balanced, with an input circuit that allows its RCA inputs to operate in a balanced configuration without requiring an inverter. There are two sets of inputs with the same flexibility as the Reference Phono 2SE, including switchable Low and High gain, seven loading options including 47k, 1000, 500, 200, 100, 50 ohms, plus Custom which can be factory-set according to your needs. In addition to standard RIAA equalization, the Reference Phono 10 also includes early Columbia and Decca equalization curves.From the first note on that treasured LP, its greatness is at once obvious and breathtaking—the Audio Research Reference Phono 10 is a sonic blockbuster that establishes the new standard in analog music playback. Emphatically. 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. The musical experience is so much more involving and persuasive—you do not want it to end.
