Audiophile grade equipment doesn't clip transients at normal listening volume. I agree that compression can help with poor quality equipment, but at the cost of permanently harming the sound on good equipment. Nobody complains about acoustic live music having too much dynamic range. The proper place for dynamic range compression is in the playback equipment, not baked into the audio data (DVDs/Blurays get this right with AC3 DRC). And compression used as an effect on individual instruments isn't what "loudness war" is referring to.

What's the dynamic range of vinyl? Usually 70 dB, whereas 16bit PCM is around 90 dB. That's what OP was probably referring to. Since the master was done for the CD then compressed for the vinyl it sounds softer/cleaner.

  CDs do have superior dynamic range, but when modern mastering squashes everything within a few dB of full scale it hardly matters. But I disagree that vinyl releases[0] typically have lower dynamic range than CD releases (most often it's the same, sometimes it's higher, and only very rarely it's lower), and I disagree that lower dynamic range sounds better on good equipment. [0] Talking about popular music only. I don't know enough about classical to say how it's done there.

    I have no actual data about the musical signals present on the discs themselves (be they made of any kind of plastic with grooves or pits), I just mentioned the technological limitations of them.

The proper place for dynamic range compression is basically upstream of anything that requires it or benefits from it. In the case of a phonograph player (which unconditionally qualifies as "poor equipment"), we have to prevent the needle from jumping out of the groove. This is downstream from the record itself, and so the signal that is on the record is manipulated.
