Reference 160S

Introduced 2019$22,000 MSRP

The Reference 160S is Audio Research's stereo-chassis take on its acclaimed Reference 160M monoblocks, packing the same eight KT150 output tubes, floating "GhostMeter" displays, and switchable Triode/Ultralinear operation into a single, more affordable box. It offers nearly the same sound quality as the monoblock pair at roughly two-thirds the price (Stereophile).
