A vacuum-tube design, it follows in the footsteps of the internationally-acclaimed 160M monaural power amplifier, introduced in 2018, which has won multiple amplifier-of the-year honors from publications such as Stereophile, Hi-Fi+, and others.

The Reference 160S (REF160S) carries-over the stunning look of the 160M, with dual GhostMeters™ that float in front of the eight KT150 output power tubes.

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.
