Here here on the headphone amp! I'm not sure the transport/DAC is really necessary, though if the Outlaws feel the need to make a unique product, that might be an option. There might be a bit of a glut of headphone amps right now, but I think there could be an opening for:

A) one that is made specifically for, say, the Sennheiser HD580/600/650.

B) A high-quality single source, single output model at $150

C) A nearly-a-stereo-preamp such as the Pro-ject Head Box (multiple sources, multiple outputs)

D) A unit with Dolby Headphone processing and a couple of outputs
