NAD C 446 Digital Media Tuner: NAD Goes Media Mad!

NAD C446 Digital Media Tuner“Digital audio in its many variations seems to yield new categories of product constantly, this new product from NAD a case in point. It will snoop for music files in your computer via its wired or wireless networks, receive AM and FM broadcasts, and search the internet for transmissions of all sorts, from faraway radio stations to specific podcasts, and send all of these directly to your high end audio system via 24-bit/192-kHz DACs (caveat coming) via RCA jacks, or by direct digital feed (Toslink). It also has a Data Port for your MP3 player when you add the appropriate dock and cable.”

Most commonly, these processes will be of the up variety to take a 44.1-kHz/16-bit signal up to 96/24, or even 192/24, in the process able to introduce noise shaping and dither to further refine…”

Assemblage D2D-1 Upsampler and DAC 2.6

Rotel RCD-991

“There’s been both misunderstanding and skepticism about the process of upsampling digital data. In recent months several DACs have appeared which do this data interpolation and bit creation, which is said to provide better sound by creating a 96-kHz/24- bit signal from a 44.1-kHz/16-bit source…”
