Once you get the Ayre set up, you won't need or have remote access to any controls for the QB-9 specifically, as it autosenses and adapts to the output bitrate (as well as displays it). If you are planning to use 24/192, select your media software to allow use of the proprietary ASIO driver provided by Ayre and Wavelength Audio, as well documented on their websites.
Herman and SFar have it right on. This must be set up on your computer as a media server and requires a USB 2.0 port directly to the DAC. (..and length, quality of the USB cable matters). The media server can then be controlled remotely in a number of ways, including iPad.
For the last bit of resolution at high bitrates, Charles Hanson recommends wired (e.g.ethernet) connections for data links and minimizing use of wireless in the near environment to reduce emi/rfi. However, the latter is IMO a tradeoff vs. the huge convenience of iPad as a controller.
BTW, you're in for an incredible experience with this DAC.
