Luxman SQ 700X (1970–1973)
A solid-state stereo integrated amplifier made in Japan, with dual phono inputs for both MM and MC cartridges.
Overview
The Luxman SQ 700X is a stereo integrated amplifier built by Luxman in Japan between 1970 and 1973. It has both MM and MC phono stages, plus tone controls and dual phono inputs, which made it a good fit for vinyl listeners of its era. It belongs to a larger lineup of Luxman amplifiers, but its exact place in the product hierarchy isn't documented. Owners describe the sound as deeply controlled with rich mids, and call it a "heavily underrated" performer next to other Luxman models.
