Since I've got iTunes Match I've upgraded my entire collection to much higher quality 256 kbps ACC files. Since its higher quality, I'd like a nice sound system set up to listen to that music in the highest quality possible. What ways can I get the music on my Mac, iPhone, or iPad into a sound system without losing any quality. Would a stereo with an iPhone dock connector play the exact digital files on my iPhone without reducing the quality? Would an Apple TV stream the exact digital files from my Mac into a stereo with an HDMI cable?
