I left it at default settings and just copied the files to the touch. The format is MP3 for both the CD and the Touch. The touch is using the full speed cable, not a usb port on the front of the CD player. I will have to check for the "loudness equalization" or "sound check" or "volume limit". It's still sounds clear at the same volume setting. Just quieter. With the cd volume setting was 22/35. with the touch it sounds like the volume is at 17/35 even though its at 22/35. I am running an Alpine DVA 9861
Just to add to Apple pissing me off. Could it be the newer IOS on the touch? I dont remember this problem with the old Nano ipod. THis goes along with what slayer1805 is stating.
