How can you hear the distortion with a noise levels that high? I would hazard an edumacated guess that the high noise levels mask the distortion. This would not surprise me as it appears to me that high noise levels in this end of the business is considered "more musical" As far as the source impedance goes the unit in question is coming to my bench in the near future.
To tell you the truth: I never thought the lack of negative feedback would increase the noise levels to the absurbly high level that I appear to be hearing. I need to ask a few questions to some of the folks who are more knowledgeable than my self. Does the error correction of negative feedback also reduce noise? It wouldn't surprise me.
