Just watch out with the bass...when you walk around, you can really hit the nodes/nulls.
If you walk more toward a corner....it might sound bigger/better...but it's just the build up.
I think what you really get with walking around or away from the mix position, is the feel of a typical listening experience, like when you have the radio going, instead of that focused, analytical monitoring experience.
Even though I might stay at my mix position...I will often just sit there, close my eyes, and play back some tunes I worked on...one after the other...and just listen to them, not staring at the screen or focusing on mix decision...but just listen to them.
It's not easy to do, because we become so tightly focused as we work on the mixes...but if you can take of the mixer's hat and just become a regular listener, you can learn to do that even at your mix position, rather than say...going to the car in order to change your listening perspective....but yeah, I often put the mix on loop, and while I'm setting up an amp or mics or just clearing things up around the studio, the music will play, and I'm concentrating on it, but I am listening to it...and it's a different experience from sitting there mixing with focus.
