Aha! But there is still a distorted ground current, and they are only halfwave !
Then make it full wave if you think that is important! Do I have to spell out everything??

With a full-wave precision rectifier, the ground current is still distorted, which will require a separate ground from the audio path. I assumed you were only considering a half-wave precision rectifier, as they are less complex.
A full-wave precision rectifier also requires two op-amps. With my high sensitivity driver, both channels can be done with a TL072, while having a perfectly clean ground current.
Also, my drive circuit has a very high input impedance, something which an unbuffered PR also doesn't have.
The more op-amps you have, the more power you draw. It all adds up...
