Well, went to Guitar Center to pick up a pair of HS8s. They were listed at $349 each, but apparently there was some sort of promotion going on, because the grand total came to $567, including tax! Pretty hefty discount, I'd say!
It's going to take some time getting used to the new monitors because they certainly sound different in my environment (and man, do those things get LOUD), but they are a significant upgrade over my previous monitors, without a doubt. The highs get a little harsh/overpowering at loud levels, which I suppose is understandable since they're less than three feet away from my ears, but it's not like I mix at that kind of level anyway. There's certainly much more clarity across the audio spectrum with these bad boys than my previous setup.
Thanks for all the feedback.
