I've got a pair of B&W 804 speakers, a Bryston B60-R integrated amplifier, a Rotel CD player, and a Pro-Ject phono player & preamp. The system is much better than my ability to understand how it works! I know that generally it's really easy to hook an Airport Express up to a stereo via an input jack and to stream music from iTunes via Airtunes. But I'm not sure how or where to hook up the Airport Express with my system--the speakers? the preamp part? the amp part?--or what sort of cable--analog? digital?--I'd need to use. I use both PC and Mac machines with iTunes, if that matters. I know this is not that complicated but I don't know what I'm doing and any advice would be much appreciated.
