About this model
The LS15 is a line-stage preamplifier, which means it has no phono stage: it switches and amplifies line-level sources such as a CD player or tuner. This one came with its original box, remote control and manual, and the seller described it as low-hours and in excellent cosmetic condition.
Unlike most equipment in this archive, the LS15 is a modern product by vintage standards, from a company that helped bring tubes back into high-end audio in the 1970s. Its inclusion here reflects the original magazine's habit of tracking collectable American tube gear of every era.
The company's earlier work is on file too, in two examples of the SP-3A-1 preamplifier. For an older American tube preamp to set beside it, there is McIntosh's C11, made from 1961 to 1963.

Does the Audio Research LS15 have a phono input?
No. LS stands for line stage, so you need a separate phono preamplifier for a turntable.
