High-End Networking Powerhouse
Designed to draw every last drop of detail from every digital audio source, 851N makes streaming and digital audio from phones, laptops, and set-top boxes sound better than you thought possible. Designed from the ground-up for serious performance, it's not only bristling with inputs and outputs, but also internally configured with high-end components.
True High-Resolution Performance
851N features ATF2 24-bit/384kHz upsampling that draws extra detail from every source (even CD, Blu-ray, and "lossless" digital files) and virtually eliminates jitter. The feature-packed 851N also offers 24-bit/192kHz native input from all sources (USB, digital inputs, Ethernet, and Wi-Fi). No matter how you store your high-resolution files, 851N ensures they sound as the creators intended.

Its outputs are equally high-end and wide-ranging, including XLR balanced and RCA unbalanced analog, digital optical and coax, plus an IR control repeater so you can hide 851N in a cupboard if so desired.
Power, Processing, and Panache
Twin AD1955 DACs configured in mono mode ensure maximum fidelity to both left and right signals, while a fully linear power supply makes optimal use of the audiophile-grade toroidal transformer.
