• A central element of Son Ultime's demonstrations, chosen by Nicolas for its impact, precision and exceptional ability to control Bowers & Wilkins speakers.

📝 Product presentation

The Audio Research Reference 160M MkII represents the pinnacle of monophonic tube amplification according to Audio Research. This MkII evolution significantly improves upon the original model's architecture through optimized filtering, even more refined internal components, and a considerably reduced noise floor. The result is a more dynamic, quieter, and even more natural sound reproduction.

Each unit uses four KT150 tubes capable of delivering ample power while maintaining remarkable transparency. The choice between Ultralinear and Triode modes allows the amplification to be tailored to the character of the installation: breadth and authority in Ultralinear, harmonic richness and intimacy in Triode.

At Son Ultime, the 160M MkII is a natural partner for Bowers & Wilkins speakers, particularly the 802 D4, 801 D4, and their Signature versions. Nicolas frequently uses it to demonstrate the full potential of these highly resolving speakers: soundstage depth, micro-detail, dynamic impact, and a sense of realism that impresses even the most seasoned audiophiles.

✔️ Conclusion: His Ultimate Sound

For Nicolas and the Son Ultime team, the Reference 160M MkII is one of the most accomplished amplifiers ever produced by Audio Research. Its transparency, controlled power, and ability to reveal every nuance of a pair of Bowers & Wilkins speakers make it an uncompromising choice for enthusiasts seeking the ultimate listening experience.
