This product does not even have six analog inputs, useful in case someone has an optical disc player that decodes providing an analog out (such as the old Oppo players). If that were the case then it would be something reasonable, a 6 channel analog pre-amp with a gimmick for a bonus. The "stereo to multichannel" so-called feature is abject silliness. Dolby and dts provide superior post processing for this purpose, and basically any AVR, even the lowest end, provide numerous post processing options. The Syn is also a poor deal, no amplifiers, means, more cables and the pre-amp is just the beginning.
One person mentioned that they couldn't find and AVR small enough and most were ugly. Yes! This is true. However, an AVR can be hidden away in a cabinet (with vent holes of course) and controlled by a handy iPhone or Android app.
I hope that this product is a market place failure. The manufacturer should be ashamed to market such a scam. This is something that naive folks will waste money on. It looks like sucker bait to sell power amps. As an April Fool's joke it would have been great. As something real, it is shameful.
