When the Reference 600 Power Amplifier was introduced in 1995 it set a new standard for High Definition® in music reproduction. In every meaningful category, the Reference 600 - 300 amplifier series remained at the pinnacle of audiophile performance. Now the REF600-300 legacy continues with a new flagship from Audio Research: the Reference 610T monoblock.     Like its pr...[more]

The Reference 750 SE monoblock amplifier continues the story begun 20 years ago with the introduction of the Reference 600; that is, to create the ultimate, tube-driven amplifier with enough power to drive any speaker load and to provide a musical experience unlike any before it. The Reference 750 SE redefines all expectations of what is possible from an amplifier in a music playback system....[more]

Bound to become an "Audio Legend", truly remarkable.Ricardo FranassoviciIn April of 1970 Audio Research was founded as the sole American manufacturer of exclusively vacuum-tube preamplifiers and power amplifiers. Along the way, many Audio Research models became benchmarks and collectors’ items as the company steadily built a reputation for great performance and great value. It was never...[more]

Incorporating the strongest aspects of the CD3MKII - its rugged construction, the Philips Pro2 laser mechanism, the Crystal 24-bit DAC, its user-friendly menu of useful features and functions - the REF-CD7 breaks new ground with a gain stage taken directly from the REF3, incorporating the latest proprietary capacitor technology found only in Audio Research Reference components. Using four 6H30 tri...[more]

The experience begins with the intuitive graphic interface, guiding the user easily through input selection and the appropriate menus to begin music playback With nine different ways to connect, plus a built-in internet radio tuner, virtually all digital sources in your system are connectable to the Reference DAC. Inputs providing metadata will allow track and album information to be displayed....[more]

The REF Phono stage is an all-vacuum-tube design.  Of the 14-tube total, eleven 6922 twin triodes are used in a unique single-ended signal path. High voltage rectification utilizes a 5AR4 / GZ34, while regulation is accomplished using a 6L6GC controlled by another 6922.  For the analog music purist, this is the phono stage to make everyone happy!  Using chassis construction and dime...[more]

The Audio Research Reference Phono 2 SE offers an extensive feature set. There are two separate sets of inputs, with selectable gain between Low (51dB BAL / 45dB SE) and High (74dB BAL / 68dB SE). There are seven loading selections including 47K, 1000, 500, 200, 100, 50 ohms, and Custom, which we can factory-set according to your need. 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 thick front panel simply has an On/Off switch and corresponding LED and does not contain the vacuum-fluorescent display found on its more powerful siblings.  The attractive internal layout is similar in appearance to the REF210 with the right and left channel boards mounted horizontally, flanking the transformers mounted on a raised central channel running front-to-back. A small LCD displ...[more]
