Seems kinda like the DIY version of the iMod. Seeing as how it removes the PCB board traces, replaces caps, etc. But instead of using the HP jack, it still uses the dock connection.

Seems like it could be fairly easily done on your own. I haven't seen the pics myself, as I'm not a member of ipastudio, but this was on another forum, and was curious if any of you DIYers did this? how do you think this SQ wise compares to the iMod? "Will it sound as good as my meridian CDP????" lol.

i have done this mod on my 3rd gen and also experimented on a 4th gen. i have reterminated it on the hp jack instead for both with good results.

I doubt the iMod is on a level superior to that of this modification. I hope to see people consider DIY options more often in the future.
