I have a Philips 47" HD TV bought back in late 2008 that has speakers on the backside of the TV, which I do not like. What I would like to do is buy an audio unit that I can hook up to my AppleTV and also regular speakers that I've had forever ( ones that actually take speaker wire hook-ups ). Any suggestions on what I should get? Preferrably something within the price range of $100-$200. Is there a certain receiver unit which would have a digital optical cable IN and regular positive/negative speaker wires running OUT?
