I agree with the post from Duke as well. I have a pair of Aerial 7Bs and was having the same problem with too much brightness. I tilted my speakers back at first by just putting a couple of 1" wood blocks under the front feet of my speakers. This made a substantial difference and really help the tonal balance. I also ended up getting rid of my upsampling dac and purchased a nos tube dac, now this really fixed the issue. Good luck!
