Just recently I have been playing around with cords and cheap ($500) powerline conditioners. During that experimentation I found some interesting things could happen
One: rum a really small cord to your amp... 18 gage or less, it will cut your low frequencies and make them seem thinner but clearer.and the rest of the material sounds cleaner. A balance between too lean and normal is just some experimenting away... even a section of narrow wire in the powercord line... The effect is as if before: a thick woolly rinocerous was in the room: add the skiny wire and the bass becomes unwooly, cleaner... more angular. And cheaper than to buy a crummy EQ box.
Also try padding up one side/corner with drapes, heavy throw pillows in the corner angles on the floor.
