In addition to standard RIAA phono equalization, the Reference...[more]

Audio Research founder William Z. Johnson was never one to follow popular trends; Audio Research began building vacuum tube components as transistors were replacing tubes for their low cost and simple maintenance. But the fact remained that vacuum tubes simply sounded better. Digital technologies arrived in the mid-1980’s, and offered a level of convenience and low maintenance...[more]

Physically, the Reference Phono 2 is similar to the other Reference preamplifiers, with slab side panels, a vacuum-fluorescent display, and the same height and depth as its predecessors. The front panel has six control buttons for Power, Input, Gain, Load, RIAA and Mute. New silver handles are standard on natural-anodized units, while black handles come with black-anodized units. For owners wan...[more]

The ebb and flow of a bass line, percussive textures, and time changes now make more musical sense as you hear them revealed by the greater immediacy and dynamic freedom of the REF2MKII. Finally, the MKII presents the music with a solidity and focus and coherence that is simply not present to the same degree in the original. From top to bottom, then, the REF2MKII is a another advance of the state ...[more]
