Wadia di322, Owner'S Manual

keeps Wadia at the forefront of digital 

music playback by adding expanded support for high fidelity DSD files to the Wadia line. Via the USB 

input, the di322 supports DSD64, DSD128 and DSD256 music files. PCM files with sampling rates up 

to 32-bit/384kHz – including DXD 352.8kHz and DXD 384kHz formats – can also be played through the 

USB input. With the addition of DSD support, digital music lovers can experience and enjoy some of the 

latest high resolution music offerings. Its 2 optical and 2 coaxial inputs accept music with resolutions 

up to 24-bit/192kHz, while the DIN input will allow future Wadia models to connect to the di322 at high 

performance levels.

A pair of variable balanced and unbalanced audio outputs connects the di322 to your amplifier. A high 

power headphone jack enables personal listening for those times when you want a truly intimate listening 

experience. A modern design with a top glass panel and aluminum construction adds aesthetic beauty. 

Combine the di322 with the m330 media server and a315 or a340 amplifiers for a complete system 

solution.
