Maybe after I'm settled I'll do a more thorough test. Telemon is right
to point out that, if such a comparison is to be done correctly, there
are a lot of variables to control for.

You might consider the H-800. It's available in the US and would easily
outperform the AN LP-1. It's small and easy to locate in a quiet spot.
Unlike the Sony loop, you could mount it outdoors, which is key. An
excellent value for the money. I'm surprised that it doesn't get more
positive press, but then I don't think the guys at LF Engineering have
worked that hard to market it.

LF Engineering is a good company to deal with, by the way. I found them
to be very helpful.

I know a couple of people who've complained that they had overload
problems with the H-800. I suspect this was more the fault of their
receivers than the H-800. However, in any case, these problems would
disappear with a good high pass filter.
