Having bought some Depeche Mode CD and DVD collectors editions a few months back and having listened to the CD's a few times and now having the Onk. amp i would see how the 5.1 sounded through it on the DVD. well while i was listening to the DVD's i was having a look and read of all the printed words on the packaging. when i saw the words super audio CD and the SACD logo very small. so i am now listening to some discs that i knew quite well but now sound better. Happy days. But why not advertise the fact on the packaging better?
