Took a while over building this one. Central to the system is AppleTV feeding my Yamaha receiver. Output is to LG 55UB8500 3D 4K TV and a mix of Martin Logan, Polk Audio and Definitive Technology speakers. Control is via Yamaha's iPad app, which takes care of all receiver functions and Apple's Remote app which keeps an eye on AppleTV and iTunes. There are also a couple of Apple routers in there; an Extreme and an Express. Another Extreme lives downstairs. Network is monitored by Apple's Airport Utility on Mac and iPad. Other input sources are Panasonic BluRay, Sony CD carousel, Windows PC running Foobar2000 and MacBookPro running iTunes. Ancillary equipment: Cambridge Audio DACMagic Plus digital analog converter, Panlong SPDIF 4x2 matrix, Sony wireless headphones, Sennheiser, Sony, Bose and Panasonic wired headphones.
