Cambridge Audio 851N (BK) Reference digital pre-amp w/ streaming

Let your digital music take flight Every Cambridge Audio component we've heard has impressed us, and that goes double for their high-performance Azur series. The versatile 851N gives today's audiophiles easy access to their favorite digital music sources.

That happens for all incoming audio data - whether it's from an Internet radio stream, a lossless FLAC file on a USB flash drive, or a connected component like a CD transport.

The upsampled audio signal is then fed through twin Analog Devices 24-bit DACs, for clean, detailed, noise-free sound and outstanding stereo imaging with every source. The 851N also inclu
