To ensure the utmost flexibility, to ensure perfect matching to a wide range of cartridges, the E-Glo provides capacitance loading for moving-magnet types in six user-switchable steps from 47pf to 900pF. ‘The loading resistance for moving-coil cartridges is continuously adjustable,’ says Lichtenegger, ‘as we already have on our Phono Box RS.’ Ensuring quiet operation is ...[more]

Elegant high-end tube phono pre-amplifier with ultra slim design! E-glo S – is a hybrid phono preamplifier that utIlizes ECC83 tubes (twin triode) in the first and second gain stages In order to get higher gain and lower noise we use in the first stage a cascode connection of tube with with two paralelly connected low-noise J-FET transistors. RIAA curve is equalised fully passive ...[more]

A 100% shielding Phono chassis where needed. SoftStart™ circuit for extended life of sensitive components, plus a reduced chance of tube f...[more]

REFERENCE PHONO 10 PHONO PREAMPLIFIER 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 firs...[more]

The LP1 has 47dB of gain, perfect for higher output (>1.0mV) phono cartridges. It is a hybrid design utilizing one 6H30 tube, special low noise JFETs, custom Audio Research designed power transformer (made in the U.S.), and multiple stages of regulation. There is no overall feedback, and it is non-inverting.  Inputs and outputs are single-ended. Controls are as simple with switches for Pow...[more]

The choices of the load are 47K, 1000, 500, 200 or 100 ohms. All functions are duplicated on the remote control. The rear panel includes a pair of single-ended inputs, a ground, and a 15A IEC connector. The PH6 is a hybrid (like PH5), with high-gain JFET input constant current and stadiuo stabilization without any counter-reaction. The PH6 uses four 6H30 twin triodes. Instead of replacin...[more]

The PH7 has 57.5 dB of overall gain, and features one pair of single-ended inputs and outputs. Full remote control is provided for all functions, coupled to an easily readable front-panel vacuum-fluorescent display. The display shows all selected functions including loading (47K, 1K, 500, 200, 100 ohms), as well as accumulated hours of operation. Display intensity can be adjusted to one of eight l...[more]

Operationally, the PH8 maintains the flexibility and ease of operation of its predecessor, with loading (47K, 1K, 500, 200, 100 ohms), Stereo/Mono, Muting andPower buttons under a vacuum fluorescent display that has eight selectable brightness levels. The display can be turned off, with nine small pixels remaining dimly lit to remind one that the supplied remote control. There is one set of single...[more]

Incorporating the best electronic elements of the original ProLogue Three, plus selected ground-breaking features from the more advanced DiaLogue Series, the next generation ProLogue Premium Preamplifier is an engineering marvel — setting a new benchmark in high-performance audio with the following features: *Home theater pass-thru. Straight from the critically-acclaimed DiaLogue Seri...[more]

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 sepa...[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]
