I jumped into the multichannel audio when I first bought my system a few years back. I bought a Denon 2200 specifically so I could listen to DVDA and SACD. To date, I have about 5 discs of music I like. As others have said, it really depends on your taste of music. You might find that there aren't a lot discs available for you.

In hindsight, I would've preferred to spend the money on a dedicated audio CD player, like a tube one. Or even look at vinyl to enjoy the eclectic jazz and classical.
