This product is the same generation as the one I already owned and used for years but somehow it works better than mine ever did. Not only does it more quickly respond but it also has an added option on my iMac speaker icon that makes it possible to pipe the sound from what's on my computer screen to my Polk Audio speakers powered by an antique S.A.E. sound system. I mainly use the AppleTV to adapt iTunes to that old stereo system as it has the audio output jacks that are required. The one I was using got too hot to quick and then I'd have to let it cool down. I am exceptionally satisfied with this purchase as it solved what I consider to have been a big problem for me. Thank You!
