My experience burning 10,000s of CDRs for musicians (masters and copies) on an Alesis Masterlink has been that occasionally, the CDRs will sound better than the original pressed CD. Generally, they sound the same. I've only used TY and Mam-A Gold CDRs since 1990s.
However, I demagnetize both surfaces and the player drawer prior to use using a Walker Talisman (easier and quicker than the Acoustic Revive CD1 (now they're up to a CD3 version). Demagnetizing makes a significant difference compared every time versus the difference between a first generation burned CDR and the original pressed disc.
Also, it is correct that multiple generation copies sound worse, probably due to R/W errors introduced into the copies.
