Hello,
I don’t know if changing your speakers or front end is an option. Revel speakers can correct this due to the wave guide on the tweeters. Especially if you go to the BE series. If you do not want to do that then I would talk to Straightwire. They specialize in helping with these issues. I think the Expresivo 1 or 2 will help with your concerns. You should give them a call. Another idea is to change the power cables. If you go to solid core or a pretty thick gauge like 9 or 10 that should mellow out the sound a little. Also up the gauge to 12 gauge or larger especially on the preamp. Straightwire Black Thunder will do nice. If you can afford the pro Thunder for the amp pull the trigger. You will be amazed how good this sounds. I hope some of these ideas will help.
