Descriptions in the literature kinda-sorta remind me of the Hafler Circuit a bit. Sum-difference sound distribution, only with a lot more technology applied.

I keep an original Dynaquad device (as well as a fully operational Advent 500). Perhaps I should hook them up? I have plenty of speakers and amps to do so.
Thoughts?
