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.
