Beautiful room.

Too bad it's an acoustic nightmare. It's a good thing you're a casual listener Byung, because getting it right in that room would require some serious room treatments.

Your speaker locations suck. Sorry, there's just no way to dilute that. From the picture, it looks like the best location would be to get a flat panel monitor, mount it above the fireplace and then have your speakers located on that wall (the left wall in the pic).
