I don't have an R2R-11, but I do have 2 Audio GD Amps (DAC-19 & NOS 19), both of which output 2.5v (there is no high/lo setting). This is 25% higher than the nominal 2v output typical of most DACs (my previous DACs were both ~2v output).
Reason I mention this is that any DAC you have will fit into an overall system gain structure, which is totally different for each system/person. So for someone whose system is moderate at this point (ie, find yourself really cranking the volume pot of HP amp and/or preamp-to-speakers), then maybe the R2R-11's high gain output is just what the doctor ordered.
But if you're like me w/too much system gain, the low output might be ideal.
I personally have never heard any sonic differences assoc. w/gain from DACs or HP amps.
