Audio Research LS3 Preamplifier Super Clean Condition Working Perfectly and extremely quite low noise MADE IN USA Description : The Audio Research LS3 preamplifier is designed to last through its elegant engineering design, exacting selection of quality components and intelligent, caring manufacture, and retaining remarkable value well into the future. It features an all-new circuit design that combines a shortest-signal-path layout with minimum of point-to-point wiring, D.C.-coupled inputs and a tightly regulated power supply. The input selector switch is board-mounted as close to the inputs as possible, and for extra high-purity input sources there is the Direct Gain Path, which bypasses all controls and switching functions except for Gain. It has enough inputs and outputs to allow connection to many sources and to a video surround-sound processor. The Audio Research LS3 has two sets of single-ended outputs, so two separate power amplifiers can be easily driven in a bi-amped system. The Audio Research LS3 preamplifier runs silently without coloring the music especially at low volumes. It has great depth and detail, but the program source makes the biggest difference. Poor recordings can sometimes sound quite harsh, yet good recordings just blossom with impact, speed and realism. The LS3 is stunning in its clarity, detail and utter simplicity. From small ensemble baroque to big symphonic pieces, the LS3’s performance is beyond reproach. Voices are very lifelike, smooth and clear, and lyrics of the song can be easily heard and understood. The detail runs deep into music and every single instrument on recordings is clear and well separated. The Audio Research LS3 preamplifier plays without adding any its own signature, and reproduces astounding resolution of musical detail, with wide-open dynamics.

ORIGINAL AUDIO RESEARCH LS3/LS3B MKII OWNERS MANUAL NICE

AUDIO Research LS 3 Preamplifier. in excellent condition. Works perfectly.

Up for sale is an Audio Research LS3B preamplifier. This is a line preamplifier (No phono section). No remote control. The condition is very good both functionally and cosmetically. This unit comes with manual and shipping box. Buyer pays for shipping.

Here is the famous LS3B from one of the best makers of pre-amplifiers and line stage amplifiers in the World - Audio Research. One owner and bought new in 1993, the B in the name signifies that this is the Balanced version, which was a £500 option. For the first 20yrs of its life, it was only used at weekends due to work commitments, and as you can see it is in marvellous condition, with hardly a mark anywhere.One reviewer said - Is this the last preamplifier youll ever buy? Just possibly. Because the LS3 is so advanced, you may never outgrow it. You certainly wont outgrow its lucid. musical performance. The LS3 features an all-new circuit design that combines a shortest-signal-path layout with a minimum of point-to-point wiring, D.C.-coupled inputs and a tightly regulated power supply. Theres even the patented Decoupled Electrolytic Capacitor circuit* found in more expensive Audio Research products. The input selector switch is board-mounted as close to the inputs as possible, and for extra high-purity input sources there is the Direct Gain Path. which bypasses all controls and switching functions except for Gain. The result is astounding resolution of musical detail. with wide-open dynamics. Only selling due to an upgrade to a Ref3. It comes in its original double box and the original Owners Manual. With FREE shipping to most UK destinations, or come and view/collect.

Audio Research LS3 Solid State Line-Level Preamplifier. Very good condition (please see photos of all sides) and full working order. 240V ~ 50/60Hz No original packaging but will be very well packed to ensure safe shipping and promptly sent via tracked courier delivery. Description: The Audio Research LS3 is a completely new line stage amplifierdesigned to accommodate music lovers who exclusively use line levelinput sources digital or analog for the reproduction and enjoyment ofmusic in their home audio systems. For many years, Audio Research hasbeen steadily developing engineering techniques that optimize thepotential of solid state devices. Some of these techniques such as ourD.E.C. (Decoupled Electrolytic Capacitor) circuit have been awardedpatents and will only be found in Audio Research components.An all-new circuit board in the LS3 incorporates extra wide tracesand a minimum of point-to-point wiring to minimize crosstalk and keepthe signal path as short and pure as possible. Thanks to a massive,tightly regulated power supply, the LS3 will reward its owner with alifelike sense of ease and dynamic expression. To maximize theresolution of detail. all inputs are D.C. coupled, long-tail pairtopology. The Direct and Tape inputs are selected via relays, theNormal input selector switch is mounted as close to the inputs aspossible (directly on the circuit board). and the final output capacitoris included in the overall feedback loop. Normal input qualitytherefore comes closer to the well known virtues of the Direct· orBypass inputs on other Audio Research preamps while retaining theflexibility of balance control and mono/stereo switching.The front panel of the LS 3 offers a useful range of controls andswitching functions without extraneous bells and whistles. Includedare Gain. Balance, Mode and Input Selectors. Muting is automatic atturn-on and in brown-out conditions, as well as manually switchable. Inaddition. the LS3 includes an important new signal route called theDirect Gain Path. This set of inputs offers the user a high puritysignal path for audiophile-quality program sources (CD players, DACprocessors, etc.) a route which bypasses all controls and switchingfunctions except for Gain. The Direct Gain Path is selectable from afront panel toggle switch, while other inputs are chosen through theInput Selector. Also included on the LS3 are two sets of main outputsfor use with bi-wired systems, surround-sound or other signalprocessors. Frequency response: 2Hz to 100kHzTotal harmonic distortion: 0.01%Gain: 18dB (line)Signal to noise ratio: 100dB (line)Output: 2V (Pre out), 35V (Pre out Max)Dimensions: 480 x 134 x 260mmWeight: 5kgYear: 1993
