And you did rip your CDs using the Control 15?
The volume 'offset' information is created during the ripping process I think.
It is a mix. When I originally had difficulty setting up my C15, I re-ripped my collection at the time with the C15. However, I mostly build my CD collection in Hawaii, rip it all there to FLAC and ALAC with dBpoweramp and then download the files and update my systems when I get home.
I tried this out by deleting �The Who� �The Ultimate Collection� and re-ripping it, but I can�t hear any difference/improvement. I am not sure if I should have done the ripping process differently to make the volume levelling work. If this is the issue it would create a whole new can of worms set of questions and issues, but with my simple initial test it doesn�t seem to be.
