Hmm, I see what you're saying. Well, if I ever get a job/have a bunch of cash, I'll keep that advice in mind.
But, clarify: Let's say I have $500 for a new reciver. I found it on the ground, I don't know, but it's in my hand. Why would I pay for the extra channels/inputs/decoders if I wasn't going to use them? Wouldn't the money be better spent on a solid hi-fi stereo reciver?
