From the most recent WHF review of the Simple Auio streamer:
"If you have the majority of your music collection stored on your computer, and are looking for a way to stream music throughout your house, then until recently
Sonos or
AirPlay were the obvious, mainstream choices.
But if you had any high-resolution content, you were out of luck. New UK-based company
Simple Audio, however, could be your knight in shining armour, with its Roomplayer I and Roomplayer II multi-room set-up which can handle high-resolution 24-bit/96kHz audio."
I would argue that the SBT was the obvious mainstream choice, that also has been able to handle HiRes since launch. Seems strange gap not to mention arguably the most popular streamer in the market.
