Audio Research Corporation Reference 160S

These modes allow you to tailor the amplifier's sonic character to your specific speakers and listening preferences. Ultralinear mode provides maximum power and dynamic punch, while Triode mode offers a softer, more intimate, and harmonically rich presentation.

The proprietary auto-bias circuit eliminates the need for manual adjustments as your tubes age. It continuously monitors and adjusts the bias for each tube, ensuring optimal performance and longevity without requiring you to use a multimeter or perform complex calibration.

The amplifier is highly versatile, featuring dedicated output taps for 4, 8, and 16-ohm speaker impedances. This ensures you can achieve an ideal impedance match for a wide range of high-end loudspeaker designs.

The four-layer board is engineered to minimize noise and interference, creating a 'darker' background. By isolating sensitive signal paths from power delivery, it allows the amplifier to reveal finer micro-details and textures in your music that might otherwise be masked.

Yes, the Reference 160S supports both balanced (XLR) and single-ended (RCA) inputs. This flexibility allows it to integrate seamlessly into a variety of high-end audio systems regardless of your preamplifier's output configuration.

Due to its substantial 100-pound weight and dimensions, you need a sturdy, well-ventilated equipment rack or stand. Ensure the surface is rated for the weight and that there is sufficient clearance above and around the unit to allow for proper heat dissipation from the tubes.
