Just a side comment - you may already know. If you choose DTS MA, make sure your receiver explicitly supports DTS "Master Audio". If it supports "DTS" generally, that may not be enough. An older DTS player can still play DTS Master Audio files, but it will only use the legacy-compatible part of the file, and that part will actually be lossy encoded. The "Master Audio" part of the stream is needed to make it lossless, but would be ignored by older DTS players.
