I can't tell you how they sound, but I can tell you I wouldn't touch Harmon stuff again after the AVR 4000 I had gave up the ghost at less than 2 years old, (humming in all modes, nothing to do with grounding or shorting) and the Harmon DVD 10 was replaced within months as it could not tolerate anything but perfect discs.
Have a look at the build quality before you decide. Maybe I was just unlucky....
