ARC just released the new Reference 160S (stereo).
Following the example of the internationally-acclaimed 160M monaural power amplifier introduced in 2018, the Reference 160S (REF160S) is a vacuum-tube design with dual transparent power meters that float in front of the eight KT150 output power tubes. Power rating is 140 WP. Price is $20,000.
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. Additionally, the 160S offers a four-layer circuit board, allowing music to emanate from a jet-black background. Weight is 100 pounds.
