Just picked up one of these blu-rays over at AIX Records:
Goldberg Variations Acoustica in 3D
Been dying to get 3D content for my new setup, and this one both looks and sounds great! HD 96/24 surround and stereo mixes available on this 50 minute or so jam of Bach's piece. Audio quality is simply breath-taking! Really utilizes the depth of 3D to make your screen pop out at you as well.
Apparently they will have more 3D releases to follow, if anyone is looking for high quality content to view.
