I currently have a PC DAW and have an RME Multiface II. I was thinking of getting one of these Boss BR-900 thingies for the following reasons.

1. To have a seperate digital recorder to mix down to.

2. To record live events using two condenser mics in stereo.


My question is how is the quality of AD converstion in one of these BR Gadgets in comparison to my RME converters?
