Steve, that 10% THD rating is actually in accord with one of the established standards; it's the so-called "maximum output" under the JEITA(Japanese Electronics and Information Technology Industries Association)standard. Of course, it's generally considered that THD when listening to music becomes significant above 1% or so, and that 10% would be very audible, but the rating under a U.S. FTC(not FCC, incidentally)rating under 1% would probably still be significantly powerful, since distortion is shooting up rapidly when it rises above 1%.
So, that receiver might be tolerable for use with better speakers within the lower power limit.
