I haven't done anything to the iPod mini since the biggest compact flash card I have is 128MB, and the iPod won't connect to the computer. If you open it up, you can immediately identify the target caps, but I will take pictures for convenience.

Which iPod are you looking at? I posted all the datasheets of the known Wolfsons on the OP.

From what I understand, you want to leave the rest of the path untouched save for replacing the coupling caps with BGs. I can't guarantee what kind of sound improvement/change you'll have, but I wouldn't recommend traveling your path. What you're doing is passing a "high quality signal" from the BG through the muddy waters of the rest of the weak amplifier circuit we've all been trying to bypass. Think of the newbie audiophile pairing a $1000 CD player with $10 headphones. He spent so many dollars just to have the purity of the signal crushed anyway. You have so many weak links in your chain (SMD resistors, cheap opamp stage, etc.) that it probably wouldn't be worth the trouble. I can't identify the line out dock pins in the
iPodlinux 3G PCB images, but if you can find them, you should do it. Then again, I found desoldering the inductors in the 4G iPod pretty intimidating, but it can still be done with loads of patience and confidence.
