Balanced Pre-outs?

[Josh]

Here's the deal:

My wonderful girlfriend surprised me for my birthday (not for a few weeks - we are impatient people) with a Denon 2308CI. As I already have a Denon 887, this receiver does little for me (or any Blu-ray owner, for that matter) because it doesn't do Dolby TrueHD or DTS Master Audio. So we're going to return it tomorrow.

Initially, I was going to get the Denon 2808 so get the decoding, but now that I have read up on it, everyone says to go for the 3808 because of the better menus and network updating.

Eventually, I'm going to do a pre/pro and amp set-up. This doesn't cause much of an issue with getting the 3808, because I can very easily use that as a pre/pro and hook it up to a 7 channel Outlaw for some serious cranking power. But then I see these "Balanced XLR" pre-outs plugs that some pre/pros are using - and being that I am all about having the best of the best - now I'm thinking I want an amp with balanced pre-outs.

Are balanced pre-outs really that much superior to standard pre-outs? Should I hold off on the Denon 3808 purchase until someone makes a pre/pro with balanced pre-outs?
