Here at the stuido we do not make discs over 8x. We are not sure that older consumer players could play them reliably. The problem could be much more difficult dupping CDG at higher speeds. If someone can do it ...more power
The only job we had with dupping CDG's was a back up of a collection for a business....and we did it at 4X disc to disc. It was 400 discs and only a couple errors dealing with longer playing times than our media could provide.
That was a hundred hours....Christ were we tired !!!
I am not aware that commercial discs are high speed duped though...I believe they are pressed and coated. I have listened to many karoke discs that clients bring in and they sure do have many audio problems. It is not uncommon for me to not only record and process the clients voice....but also process the music too. There can be some real grungy audio....and it did not come from the master recordings....it comes from the CDG disc production.
When we need to burn a lot of discs ..we don't burn them faster...we just ethernet the audio to all the other Macs in the building which all have 8x burners including that old 4X yamaha 400t !
