Really. No one is doing anything about CD pre-emphasis. Surely that must be making some ears bleed. I only have a couple pre-emphasized CDs. But always cringe to listen to without de-emphasis. With de-emphasis applied they blend so much better with the rest of the library without constantly adjusting the treble every time a track from them plays.

I'm using VLC to rip CDs and SoX to apply the de-emphasis.

What are you using?

I'm not sure I have any CD with pre-emphasis and I've ripped them all (thousands) to FLAC :?

I don't have tone controls either so I presume I'd notice if there was a problem.

Is there a list of CDs that used pre-emphasis?

For Abbey Road and The Dark Side of the Moon, I used an FFT filter to de-emphasize the files. That was years ago. There are simpler and less time-consuming ways to do this, but this yielded the best sounding result, IMO.
