Very cool, glad you're liking.
I've been enjoying the Airmotiv 4's a fair bit as well. Have a simple setup of DVD player -> Benchmark DAC-2 -> (balanced to) Airmotiv's. In the spirit of Mapleshade, my 4's are on the carpet angled up via cork/rubber combo footers.
Somewhat muddy midbass, but pretty fun! May try to put them up on butcher blocks, even more Mapleshady.
