There were a number of excellent new digital audio products at RMAF 2011 that are omitted from the above list:<br />
<br />
1. dB Audio Labs' new battery-powered Asynchronous USB DAC; supports up to 24/192 files (debuted at RMAF)<br />
<br />
2. The new Mach 2 Music Mac Mini OSX Lion music server running from a PI Audio BatteryBuss (that also powered the connected hard drive) (debuted at RMAF)<br />
<br />
3. Auraliti linux-based music servers (of various types)<br />
<br />
4. Empirical Audio Overdrive Ultra DAC (debuted at RMAF)<br />
<br />
5. Red Wine Audio battery powered DACs (with USB input)<br />
<br />
The dB Audio Labs DAC and Mach 2 Music server ran the room that The Absolute Sound awarded Best Sound for the Money. Very interesting that all of these manufacturers get zero mention here.
