Touted to be even better than the LS2. “..the LS3 appeared to replicate the overall performance of the LS2, and then some…”
by Martin Colloms, Stereophile Magazine Vol 16 No. 8



Audio Research LS3 preamp runs silently without coloring the music especially at low volumes.
It has great depth and detail.

The LS3 is stunning in its clarity, detail and utter simplicity.
From small ensemble baroque to big symphonic pieves, LS3’s performance is beyond reproach.

Voices are lifelike, smooth and clear.
The detail runs deep into music and every single instrument on recordings is clear and well separated.

It reproduces astounding resolution of musical detail, with wide-open dynamics.
Great tight bass, real midrange and detailed highs.
