Need help with acoustic treatment for brightness.

I have switched back to my Forte Model 40 preamp (Pass designed). I like it for it's fantastic detail. However it has given my system a mild brightness issue at around 5000Hz. I have read that absorptive material at the first reflection point can help tame this. In my case, the primary first reflection point is on the ceiling so the solution is not as simple as hanging a rug on the wall. My budget is about $100 so DIY is most likely. John Marks of Stereophile uses RPG Skyline diffusors on the ceiling for his speakers. Could diffusion tame brightness? If not, Is absorption the key? I've used a lot of interconnects and that doesn't solve it.

One thing you might try is changing the angle of your speakers and, if they're monitors, the height too. Some say as a rule of thumb that it is preferable to have a slight upward tilt with the tweeter at a height just below your ears at listening position. Like everything to do with speaker placement, your results may vary, so try some small changes and see.

Another Hail Mary attempt is, if your speakers are bi-wirable, make your connection to the woofer side of the terminal pairs.
