I am selling a Cambridge Audio 851N; streamer, DAC, and preamplifier. The Cambridge Audio 851N work perfectly, no scratches or blemishes, operates flawlessly and offers serious high end sound. It is a superior machine in terms of construction and performance compared to those currently in the catalog. you can enjoy your music library on the 851N without having to convert or replace files. The 851N supports high-resolution files including ALAC, WAV, FLAC, AIFF, WMA, MP3, AAC, HE AAC, AAC+, and OGG Vorbis.
