Yep, you should give this piece a listen. It is really great, if not marvelous - sound wise.
1. The concept of the RS20i is a bit different as you assume. Dirac is applied to all output ports and you can't have it on specific channels. It applies to all channels but you can have about 20 storage spaces for different measurements. I use it to switch from no screen and with screen e.g. but with the same set of speakers.
2. I have some addendum's to the 1.02 manual, describing the additions. There is no full manual, as far as I am aware of. However, if you have your RS20i, you can ask Datasat directly for additional manuals, above 1.02. Or I can sent them to you.
3. The digital output can be switched on and off independently. But there was a limitation in the resolution in kHz, if you use the digital output, if I remember correctly. It should be in the 1.02 manual.
4. As far as I know, not. The volume control applies to all outputs.
