After all this time, ARC is proud to finally introduce the first two-chassis phono preamplifier in our history, the Reference Phono 10. From the first note on that treasured LP, its greatness is at once obvious and breathtaking. The Reference Phono 10 is a sonic blockbuster that establishes the new standard in analog music playback.
OVERVIEW
Vinyl record playback has been an integral part of Audio Research since their founding in 1970. Think back to the great phono stages built into the defining preamplifiers of their day, among them the SP3, SP6, SP8, SP10, and SP11. Even after the introduction of the compact disc in 1982, phono sections remained a revered part of ARC’s preamplifiers.
The first Audio Research phono preamplifier in a separate chassis was introduced in 1992. This model number was designated because it mirrors its line-stage counterpart, the Reference 10, providing an unsurpassed level of performance in its category. The front panel has a 7” diagonal touch screen mounted asymmetrically, and only two buttons for power and mute. The interactive touch screen allows the user to change inputs (and input names), equalization, loading, gain, muting, foreground and background colors of the display, display intensity, and tube hours. Control functions are duplicated on the supplied metal remote. The front and side panels are 3/8” brushed and anodized aluminum, and the tops of both units are acrylic with a laser-cut perforation pattern (chosen for its sonic benefits).
From the first note on that treasured LP, its greatness is at once obvious and breathtaking. The 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. But these are mere words that pale in comparison to the actual listening experience. Understanding only comes from listening. Reference Phono 10 is the product that triumphantly validates the superiority of analog playback. Music in High Definition.
