Kan det blive bedre end Phono 10 reference - vi tvivler...

Vinyl record playback has been an integral part of Audio Research since our 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 our preamplifiers. The first Audio Research phono preamplifier in a separate chassis was introduced in 1992. After all this time, we are proud to finally introduce the first two-chassis phono preamplifier in our history, the Reference Phono 10. 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).
