Purely out of curiosity I tried plugging in a Nuforce uDac via the Apple Camera Connection Kit's connector into my iPad and a pair of Ortofon eq7's - and I must say I'm impressed. It's certainly the most portable hifi I own - very sleek, very usable, and truly hifi, leaves an iPod for dust for sure. Will do more experimenting over the next few days, but so far, so good.
