I recently saw this while checking to see if Bose was adressing it's lack of HDMI support for lossless audio.

It looked promising for my Lifestyle 28 system until I realized that it is just a pass through to add more video sources. The system still does not support LPCM, Dolby HD or DTS-HD. I figured I'd let fellow bose owners know about this so they don't spend $300 by mistake. Hope this helps.
