I was premature in reporting my "great take" running without a preamp with my CA-11's straight into the mic input. Mixing it down with a good set of monitors I discovered subtle distortion, even though the meters did not peak. Looking at the L/R waveforms, they are unbalanced a bit. My assumption is that the plug-in power without the pre/battery box was insufficient. What's disappointing is that it was not a super loud show by rock standards. Further evidence that, with it's size and low plug-in power voltage, this is not an ideal stealth rig.
