iFi GO Pod - Anyone got any experience of it, and if so is it worth it?

[turbohobbit]

I'm mildly tempted to drop a significant amount of cash on a pair of iFi Go Pods for my Shure Aonic 5s but given that they're more than the IEMs themselves I would like some reassurance that they're actually worth it before splashing the cash. SO, I was wondering if anyone here had any experience with them, and if so what their thoughts are on performance, worth, etc. Cheers in advance!
