It feels like you have headphones on doesn't it?
You can also add a volume booster and equalizer via an app called Boom. It's $5 and available from the Mac App Store. To me, it further enhances the sound without introducing distortion. You can also try it first here:

Uh is this awesome sound in the 13" too?
I was blown away by the jump of the speakers on the original rMBP, but the new one's speakers are even better than that. Any previous rMBP owners notice the difference?
