Hi, The only Apple device I have is an iphone (which I love) I use a Yamaha amp which supports Airplay and it (the airplay part) works brilliantly. Looking to connect an Airport Extreme by ethernet to a sound system in the shed to use airplay. Might try it connected by wifi first, but I realise wired is always better. I would also set it as a wifi extender but my requirements as far as wifi are minimal and could easily live with out it or a minimal speed increase. Main concern is getting the Airplay to my sound system. Would there be any noticable advantage (sound and reliability wise) to paying top dollar for the latest AC model Airport Extreme or would an earlier model like maybe a A1301 3rd gen or later model work as well for a fraction of the price? Keep in mind I would be connecting to my router by ethernet cable, so wifi strength/bandwidth would be of little consequence. Please keep in mind I'm only connecting to a budget sound system in the shed. Thanks in advance for your advice.
