[QUOTE="damongold, post: 1535973, member: 310777"] Mpeg 4 Audio = M4A. weather it says "lossless" or not it's still .m4a. either way both lossless or packed they both degrade the quality, the only difference is "lossless" uses the unused bits in the words downstream to "pack in" the high level bits of the previous words to even out the bit rate. so technically no data is lost but the re-assembly of data does take time (usually under a millisecond) and has an undesirable effect on the low frequency transients (causing a "soft" low end) and corrupts the phasing of the source material giving it a less punchy and less defined character. im still a huge fan of DSD and SACD but it very hard to find content in that format and with Spectral being bought buy Avid it could be the end of those formats (gone the way of Beta) [/QUOTE]
