The Audio Research SP17 features low-noise JFET inputs in both the line- and phono-stages, and instead of 12AX7s you will find a 6H30 in each section – all of our preamplifiers now employ this high performance long-life tube. The same high-voltage regulator found in the LS17 and LS26 is now utilized in the  Audio Research SP17, and so is the same 103-step volume control – the SP16...[more]

Also for the first time, the Input selector is on the left, the Volume control is on the right.Through the touchscreen one can change Inputs, select Stereo or Mono, Mute, adjust Phase, adjust left-right Balance, and adjust the phono input Load (50, 100, 500, 1000 or 47k Ohms). Through a Settings menu, you can customize other items: change input names, adjust gain offset for each input, change volu...[more]

Its purpose is to provide the differential signal for true balanced operation, a first for this series. With both balanced and single-ended inputs (switch selected), the VM220 will be compatible with every Audio Research preamplifier. In addition, the VM220 uses a super-wide-bandwidth output transformer to provide better frequency extension, explosive musical dynamics, and more powerful bass ex...[more]

The chassis, circuit layout and feature set of the VS110 are almost identical to the VS55, but scaled up to accomodate the greater power output. The chassis itself measures 17 1/2" W by 19" D, and features an anodized, natural-finish top plate labeled with tube location/type, output-tube bias access points and the inset Audio Research logo. The chassis front holds a rocker-style power switch and g...[more]

The VS115 revisits the classic look of the VS110 with its open architecture and natural anodized top plate – now more ventilated for better heat dissipation. Drawing upon the successful REF110 input stage design, the VS115 uses a FET input with two 6H30 triodes in each channel for gain and as a cathode follower-driver for the 6550C-equipped output stage. This allows both balanced and single-ended...[more]

The VS55 makes a wonderful companion to the recently introduced SP16 preamplifier. Together, these exciting new companion products enable you to assemble a true Audio Research music system at a more reasonable cost. Like the SP16, the VS55 represents a fresh, new design direction for Audio Research. Using an open (rather than fully enclosed) chassis architecture, the VS55 features a milled, anodiz...[more]

Its rated output of 50 watts per channel does not convey the VS60's ability to drive power-hungry, low-impedance loudspeakers. Audio Research designed the VS60 with the finest full-range speakers, not compact monitors. Dynamics are lifelike with a sense of ease normally associated with larger amplifiers. Yes, its resolving power is surprising, allowing you to hear details that were previously hidd...[more]

With an unbeatable combination of great sound, cool packaging and affordable pricing, the VS55 and VS110 amplifiers have been garnering rave reviews and enjoying brisk sales around the world. We are very pleased to inform you of an addition to the series, the VSi55 Integrated Amplifier. With a rated output of 50 watts per channel and a reasonable price, a remarkable level of performance, build qu...[more]

The VSi75 integrated amplifier breaks new ground in an ‘all in one’ product design, and sets a new benchmark in the lifelike reproduction of music. The VSi75 continues the design series of ‘open chassis’ products from Audio Research such as the VSi60 and VS115, yet incorporates new developments from the Reference series product to combine in a visually striking and so...[more]
