Maybe PS Audio should make a Hafler/DynaQuad device and special speaker (styled like their other audio components and speakers)...an easy intro to surround sound.
And maybe they could also add more out of phase content to their stereo mixes so that matrix decoders (SM to Hafler passive) would have something more to route to the rear/surround speaker(s).
I plan to compose an "Ask Paul" question about adding a Hafler passive decoder to the PS Audio lineup (I'll probably mention Quadios and DV MCH SACDs too).
