Good vinyl has at best 30-40db of channel separation at 1khz, either side of this it's much worse 10-20db, compared to Redbook over 100db all across the audio band.
If you put L&R channel bleed network on the output of a cd to mimic the channel separation of vinyl then cd becomes much like vinyl to listen too, more "monoized" for want of a better word, for those that like vinyl better.
A good thing would be a switch on the back of a cd player/dacs to mimic the channel separation of vinyl.
I've done this, but with a simple crude network that destroys the separation to 30db channel separation right across the band, and to my listening it made many recordings easier to listen to (especially older ones like Beatles ect).
It's not right, but it can be much more pleasing to vinyl lovers, as it doesn't tax the brain as much, and adds a richness to the sound.
