Canadian audio manufacturer Bryston Ltd. was showing off its soon to be released SP3 surround processor at CEDIA 2011. Taking a purist approach, there's no video processing to potentially muck up the audio signal, but the unit provides convenient HDMI v1.4 video pass through from each of seven HDMI inputs, and should a higher HDMI version ever be required, modular construction insures that a factory upgrade can do the trick. The prototype on display was a 7.1-channel model that decodes all the latest Blu-ray codecs and steers the audio to either balanced or RCA outputs. There's also a pair of AES/EBU inputs and a USB input along with the usual mix of analog and digital stereo inputs. Bryston sales VP James Tanner said the SP3 uses all discreet Class A circuitry in its analog stages for optimal sound quality, and great care was taken in the circuit topology to keep incoming video signals away from the audio, including dedicated power supplies for the video and audio circuits with no shared common grounds. Price is expected to be $9,500 when the SP3 ships at the end of September.
