A few things I would like to see:

-A phase flip on 1 channel (or both, but you don't have much faceplate left for two switches) for checking the Side information.

-An active gain stage on input 3. One thing I really need out of a monitor controller is the ability to easily do level-matched A/B between the flat and processed sounds, which generally means boosting the flat version 3-10dB. I guess I could calibrate the converter feeding input 3 10dB hot, but that wouldn't help when I am working with an analog source.

-A buffered meter output.

Regarding price, look at your competition. A Crane Song Avocet runs $2400 on VintageKing.com, and includes D/A conversion. You'd have to have a fairly low price point to make your controller + converters price competitive with something like that. (Though, I do like the rackmount controller better than having a remote, I hate having a big box cluttering up my desk.)
