C'mon. This is not a problem with the guys at the AV forums. You can get high rez audio via HDMI either in the original bitstreams (LPCM, Dolby True-HD or dts-HD MA) or, if decoded in the player, all as LPCM. They will have equal resolution in both cases but the design of the particular player will determine which options are available.
In addition, if the player decodes and converts these formats internally, the same high resolution may be available on the analog outputs. Again, the design of the particular player will determine if these options are available.
AFAIK, no current player will decode dts-HD MA internally.
TOSlink and coax will handle the lossy DD/dts as well as stereo hi-rez but, again, the latter depends on the specific player.
