Bit perfect and SPDIF Passthrough

gstreamer, still is afaik not supporting digital output via spdif.
Furthermore the output is not bit perfect, a imo requierement for an audiophile player.
Would you consider to support in addition to gstreamer another sound architecture?
This could be mplayer or Xine or anything that supports spdif passthrough.
From experience i know, that the use of the softvolume option in mplayer excludes the spdif passthrough.

TIA
