If you're processing a Blu-ray disc, there is usually never a reason to convert any audio streams - with one exception, some hardware player that can't deal with DTS or something like that.
But short of that, with HD audio just keep the DTS core, or the AC3 substreams from TrueHD, or just the plain DTS/AC3 streams.

Converting any lossy codec to another lossy codec is always going to recuce the quality.
