Pioneer's SC-LX71 and SC-LX81 receivers (SC = stereo control) use the proprietary Precision Quartz Locking System (PQLS), which synchronizes data coming from similarly equipped Blu-ray players - such as the new BDP-LX71 (http://whathifi.com/home-cinema/archive/2008/05/24/news-pioneer-bdp-lx71-blu-ray-player-claims-to-redefine-the-world-of-digital-entertainment.aspx) - to the receiver, with the aim of providing accurate, faithful music reproduction.
Full tech-specs for the 'LX71 and 'LX81 have yet to be confirmed,
but they look to be 7.1 designs offering 180W and 190W per channel respectively.
The 'LX71 offers 1080p, HDMI upscaling (4 in; 1 out), while the 'LX81 endears itself to multiroom/TV+projector set-ups with 4 in; 2 out HDMI upscaling.
Pioneer claims both will deliver "robust, realistic sound quality" due to the manufacturer's Direct Energy HD Amplifier with ICEpower technology.
The 'LX81 also boasts HDMI jitter reduction and a Sampling Rate Converter for even greater sonic accuracy.
Both receivers feature Advanced MCACC tuning - which claims to ensure "accurate, studio-quality surround sound regardless of the room configuration" - plus Full Band Phase Control, designed to eliminate bass 'phase lag' often caused by low-frequency levels in 5.1 surround sound systems.
Like previous Pioneer products, the SC receivers are also DNLA (Digital Living Network Alliance) compliant, with support for Windows Vista, Windows Media Connect and Microsoft audio DRM technology. That offers the potential of streaming digital media files direct from networked computers and storage devices to your AV system
As for the jitter reduction the LX81 has over the LX71, i read this in the review of the LX81...
"It also features Network support, plus a dedicated Precision Quartz Locking System (PQLS) designed to optimise sonic performance when used with the BDP-LX71A by reducing jitter over HDMI."
So, does that mean the jitter reduction won't work from an other blue ray player like a PS3 for example??
