I'm still struggling to work out exactly what was in this concept for Grundig...(aside from using up a skip full of IR chipsets...).

Whereas Bluetooth is relatively omnidirectional to a few feet, the IR concept here would require a direct line of sight to work.

I would assume that the matching CD and DCC players would have no DAC internally, simply sending out raw binary to a master DAC in the amp. Is that correct or simply too rational for what was going on here?

Was the transmission 16-bit? 14-bit?
