Hi,
I wanted to test it by myself if there are any differences between shows which are: pre-fm | dfm | fm | pre-fm>mp3 ... -sourced!
The test is based on one track of a show which were seeded in different versions and I were so lucky to receive also the pre-fm track as reference.





1) preFM ... absolutely lossless (the version before it was broadcasted)

2) FM ... (analogue, terrestrial ... a typical broadcast before everything went digital)

3) preFM>mp3 ... (I used the preFM track to create a 192 kb/s cbr mp3 file - lame 3.97)

4) dFM ... noticeable lossy shit (satellite, DAB, whatever)

Conclusion: The thing is you don't only see the difference, you hear it CLEARLY. While the preFM version blows you away and goes under your skin, the dFM version sounds spongy like played next door and is even worse than a 192 kb/s mp3 file.
