Audio Research REF160S Arrives

  • 1 min read

The new Audio Research REF160S stereo amplifier has arrived! The REF160S is a stereo version of the REF160M monoblocks and uses an octet of KT150 output tubes to tremendous effect!

The 160S continues the feature set introduced in the 160M, including a proprietary auto-bias circuit, switchable Triode or Ultralinear modes of operation, balanced and single-ended inputs, and an output tube monitoring mode. The 160S also uses a four-layer circuit board, allowing music to emanate from a jet-black background.
