Can you describe your room? size, etc...? for example here's my situation....
I have an 11x12' room with a 2' deep bay window. I sit facing the bay window. I moved from a very large room to a very small one and have found that I have a lot more control than I would've in the larger room. I too, ordered 8th nerve's stuff... but, I added some home-made products based on 8th's philosophies already and that really helped. If you have a big problem, you may have to do a big solution.
I have home-made seams running almost the entire length of each corner of the room. That made the sound a lot less congested. Adding a rug got rid of some room reflections as well. I bought a floorstander to put in a doorway and some corners to finish the room. I feel like this will be a huge improvement. The room already sounds 'cozy'. It's not dead or overly lively. New curtains should help a little high frequency glare I'm getting of my bay window.
I'm doing all this now because I am waiting on equipment to arrive. I have 2 preamps, a pair of speakers, and new speaker wire all on their way. Hopefully it'll all get here soon so I can start the break-in/burn-in process. By the time it's all together, the room and system should integrate perfectly.
Best of luck!
