Yeah, had it been some other time of day, I'd have realized that. I've never tried to test a long cable, but I'm painfully aware that in it's lowest range, my LCR's capacitance results are skewed widely by whether probes are attached, and which way they happen to be jumbled around. I still need to take some time and put together some 1-inch-long probes with aligator clips . . .
People talk like a series 47ohm metal film resistor on the output of an amp is going to make some massive negative impact on either the quality or the volume, and it just isn't so. You probably won't notice any difference in loudness, and often it actually improves the sound quality. And you don't need to use one that big, either.
