No matter how well the cable transmits the modulated light, the signal still has to be converted at both ends, and the conversion electronics are as susceptible to obvious and nonobvious design problems as any other bit of audio electronics. The little boxes are fed with wallwarts and humdrum wire, so RF pollution is a strong possibility.

I heard them in my system and liked them enough to buy em!
If they only really work well with fully-charged batteries, then it seems petty to sell them with the AC supplies and charge extra for the battery packs.
What good will it do to have advantage of optical cabling (such as immunity to noise) if the source-which in this case is the light transmitter module-is putting out crappy signal.And as you said, having wallwarts and humdrum wire feeding these modules doesn't help the situation either :)

"Faster than a mugwamp on speed." It's not a crappy signal, it is not polluted, the only place where ground is connected is at the receiving rx, but only on the wall-warts. There is zero interference when using the battery, and the 'warts are only for backup purposes while charging a down battery.

C'mon, ask, don't tell.
How can you speak with authority when you're just guessing?
As I've said, the measurements were bogus and should not be taken into consideration.
