You skeptics want samples?
hear here

Yes, the 1425-84 reissue by Mitsubishi does contain both analog and digital tracks.
I offered captures of both in Post7 of this thread (I suppose the links are expired by now.)
They sound different, is the message I tried to convey in Post5.
SilverWook mentioned CX decoding in 6, and some time later it 'clicked' in my brain.

If a mastering engineer follows the rule book, then a diGital SOUND track will not have CX encoding applied. The CX logo on the jacket should refer to the analog track only. That's the way it's supposed to work.

But in this case I believe the masterer took the easy route, and didn't follow the rules. I believe this diGital SOUND track really does have CX applied, even though it shouldn't, according to the rules.

I hope you'll help me test that theory. I'll need help because I don't know how to force CX off with either of my players.
Unlike its digital track, I believe that disc's analog track is correctly mastered, which means a flag in the bitstream will tell the player to switch on its CX decoder circuit.
Some players will ignore the flag if you tell them, or allow you to turn CX on/off manually. I don't think my players will allow it.
If somebody can force CX off, and then capture the analog track (without passing through the CX decoder)
then I'll betcha the result would be quite similar to my ripped samples. That's the hypothesis anyway, which I cannot test.

To me the digital track sounds dynamically-challenged or squashed to hell. It's the way the CX compander algorithm works, as I understand it
