I currently have a Sony STR-DG720 and looking to possibly upgrade. What I need is 5.1 or 7.1 receiver that can decode True HD and DTS HD codecs, minimum 3 hdmi inputs, minimum 1 optical input. Don't need much else, already have the speakers. Doesn't need to be the most powerful either. BUT, what is important, is size. It needs to be small in terms of height. Most receivers like the one I have, are big bulky items. I'm going for minimalism and would like something that's about half the size in height as a typical receiver out there. Anything out there like that?
