At the Venetian, Avatar Acoustics' Darren Censullo set up several of the products he distributes including the Purist HDR 6D music server/DAC from AMI HiFi. Darren explains that there are seven versions of the HDR 6D and 6DA, depending on how it is configured, ranging in price from $2,500 to $25,000.

On the front is a slot for loading or playing music from discs and a clever flush-mount receptacle for putting your iPod Touch which then acts as a touch controller and display. There is also a free iPad app.

All the usual inputs and outputs are included: AES/EBU, SPDIF, USB, Ethernet, WiFi and HDMI which supports a full video player. The HDR 6D handles a wide variety of file formats up to 32bit/384kHz (on the 6DA) and the company says that sound quality is enhanced by a process that entirely caches each track for playback. Also included is upsampled Web Radio and multi-room playback.
