“Twenty basically turns any set of speakers *and an AirPlay receiver* into an amplified AirPlay wireless system.”

There, fixed it.

So it’s pretty much an integrated amp with a built-in DAC and a slot to hold a digital audio source that happens to no longer be made.

Strikes me as a device that’s showed up too late to the party.

I have been waiting for this product to be released. I have been looking for exactly this solution, and there is nothing anywhere near as slick. There are a few amplifiers available for the same price or less, but none have a Toslink optical port, they all have power bricks, and their output power is less. With refurb Airport Express units still on sale at Apple’s web store, this will be $169.  Assuming the audio quality is good, these will make some people very happy.
