Motherboard for audio

Gigabyte is the first company known to me selling a mobo with audio quality as a sales argument.
It features a dedicated USB port with clean power.
The onboard audio has socketed op-amps and adjustable gain.
They also claim to shield the analog components from noise at PCB level.

WiSA

WiSA is an open industry standard to connect speakers wireless.
It allows for lossless 24-bit audio with sample rates of  32, 44.1, 48, and 96 kHz
It supports 2 channel up to 7.1 surround.
It operates in the 5Ghz U-NII band.

At the present (2013) B&O is the only brand known to me using this standard.
As Pioneer, Onkyo, TEAC, Klipsch en Sharp are members of WiSA too, one might expect them to bring out models in the near future.
