No experience. Heard of one called delay play, too.
Wonder if you could pause a DVR 7 seconds & get them in sync much cheaper that way?
I've tried that some, with limited success.
Wonder how many speakers that will require? Not that anyone knows; to be safe, I'm buying all the Quality Klipsch I can find at reasonable, to me, prices.
