📝 Product presentation

The Audio Research Reference 160S is one of the brand's most accomplished power amplifiers. Introduced in the prestigious Reference series, it employs four KT150 tubes per channel, capable of delivering impressive power while maintaining remarkable sonic finesse. Its completely redesigned internal architecture for this generation allows for a significant reduction in noise, increased definition, and a disconcertingly natural musical presence.

The 160S offers two operating modes: Ultralinear, for maximum power and expansive dynamics, and Triode, for a more intimate, textured listening experience with exceptional harmonic density. This flexibility allows the sound signature to be adapted to different musical styles and speakers.

At Son Ultime, the REF160S is among the most compelling power amplifiers used in demonstrations of exceptional systems. Nicolas often uses it to showcase highly resolving speakers like the Bowers & Wilkins 801 D4, with results that impress with both their fluidity and their ability to create a wide, deep, and immersive soundstage.

✔️ Conclusion: His Ultimate Sound

For Nicolas and the Son Ultime team, the Reference 160S represents a perfect balance between power, finesse, and organic musicality. It's an amplifier designed for enthusiasts seeking a vibrant, textured, and emotionally resonant sound, without compromising on dynamics or presence. Its place in our high-end systems makes it an essential reference for clients wishing to experience the pinnacle of Audio Research's expertise.
