>> Comparing it to DSD is like comparing .ZIP to .JPG... they operate in different domains <<Not quite. A JPEG is usually already compressed to the max (which is why it's used so much over the internet).
Just try zipping a JPEG -- the resultant 'ZIP' file is usually not much different in size to the JPEG.
But if you zip a raw .BMP bitmap, then you get significant file-size reductions. So, a BMP is analogous to LPCM and DSD etc.
But a .ZIP file is analogous to MLP and DST etc.
AND, a JPEG is also analogous to MLP & DST, since all three are compressed 'packages', which contain a 'payload'.
And if you zip a JPEG, then you are in effect trying to compress the payload twice.
Follow Ups:
JPEG is not analogous to MLP and DST. JPEG is lossy. JPEG is analgous to MP3. As I said, MLP is analagous to FLAC and ALAC. I know damn well that ZIP is dictionary/entropy compression (mitigation of redundancy) as is MLP and DST.
The point I was trying to make is the same one you were trying to make, that comparing MLP to DSD is apples and oranges.But, you've got compulsive asshole syndrome, probably because I've listened to a SACD some time in my life.

JPEG IS a payload carrier. Just like a zipfile. Granted, in the case of JPEG, the payload is lossy -- depending on the level of compression selected when you save the file. But then it's compressed for portability. A different thing altogether.

Michi, a bit of friendly advice: This really is the wrong forum for inane Jar-Jar impersonations. There are plenty of geek forums for that, though. And I'm sure they'd welcome you with open flappy ears.
You think that was a "Jar-Jar" imitation? Yeah. Star wars used the term "massa'". You got it.Friendly fucking advice my ass, Martin. You just can't stand not showing a thing or two to someone who isn't as privilege and old as yourself.
You can split hairs, and oh for god sakes I know you will: The JPEG specification includes a container *AND* DCT compression (or just raw entropy encoding at the 'lossless' setting) to act on the image it's carrying.
You know damn well what I was trying to get across, you just couldn't resist the masturbatory satisfaction of poking holes in what wasn't a complete and watertight thesis when making a comparison between MLP and DSD.
My original point was that MLP cannot be compared to DSD, because it's not a modulation method.
Oh and, please tell me, what the fuck gives you the position and right to tell me where to go on these forums?
Please don't use the term "friendly advice". You're a liar. You're no friend of mine, so lay it out like it is: adversarial advice.

You may reply with more irrational expletives if you so wish. That is your right. However, it does not impress. Really.
