Is this the dock that Drew (Moon Audio) was recommending at RMAF, or was that the Denon dock? I need another digital dock for my main rig, since I don't think my DLO Homedock HD is an upgrade over line-out. I was looking at the Cambridge on Amazon the other day, and will take this into consideration.
I've been happy with the Nuforce iDo iPod digital dock in my bedroom rig, with the coax S/PDIF > nice DAC sounding best. But the RCA output is not far behind, although the headphone out is more on the level of the $130 uDAC-2 headphone out (bass response could be tighter; and extension, micro-detail, and ambience are not as good via headphone out). I've been using iDo daily in my bedroom rig to feed my DACmini lossless music from a 16Gb Nano. I thought I'd just buy another, but I like to try new stuff too.
The best part of the iDo is you can connect the iPad or iPod via normal sync cable and easily hold it to watch a movie or control the music. But you can also use the Apple remote to skip songs or adjust the volume if you are sitting across the room from the docked iDevice. I also like that it's powerful enough to charge the iPad. What I dislike is that iDo doesn't offer a video output, while both my DLO Homedock HD and older Homedock Deluxe have video output. And my Homedock HD has a USB port to connect to a PC to sync, while iDo doesn't have that.
