But since PCM has a variable bit rate by nature, our experience from our testing is that a lot of repertoire is in the region of 700-900 kbps. So if you are using the AAC 320 option today, you are looking at doubling plus some. But remember that if bandwidth is not an issue, decoding a lossless file is much easier � so the general experience is actually quicker than with AAC.
Not sure I buy PCM having a variable bit-rate by nature. Perhaps they mean the compressed file size?

Also, lossless is lossless. I have no idea what this Dolby encoding thingy is.
