blackcabmal:If i set an album on the mac presumably the whole album will play on the hifi without me having to select each track.
No probs - just so you know, iTunes will play through the Airport Express to your hi-fi the same as it does through speakers hooked directly up to your Mac i.e. start playing an album, it will play the whole album, start playing your entire Library on shuffle mode, it'll do that with no stops etc.
Oh, and also, the line out on the Airport Express is also an optical digital out, meaning you can hook it up to an external DAC (like the Beresford one) which should improve the sound substantially. Haven't tried it but I think John intends to so worth following that thread above! I'm pretty sure this isn't an option with the rDock / iPod lead.
