Received my Wadia i170 transport today.

does this transport support iphone?

No, it doesnt support the iPhone (at least it doesn't mention it as one that Apple products that it is made for,it may work but in my experience with products not made for the iPhone, there may be a humming sound created through your speakers) and it doesnt provide an on-screen navigation menu. You must use the iPod's screen to make your music selections. This must not be an issue for Gerryn.

I was told in the past it does, but have no experience.

I have been using my iTransport for about a week now and I am very pleased.

Got mine yesterday, and ran it for a few hours, and I am impressed. I cued up some music that I ripped to the iPod and went between my Cambridge Audio 340C and the iTransport/Keces Da-131 DAC and it sounded just as good. The remote sucks and it would be nice to be able to see the menu through the component video jacks, but other than that, its a nice piece

I guess it will sound as good as your DAC is. Something to think about. It takes two to Tango.
