I think you have an RF issue in your setup - that is why the floating shield in the Coral helped. BJC don't float the shield on their interconnects - they use straight coax cable, but the coral is twinax with a floating shield connected at one end. Is there a plasma TV nearby?
You may benefit from the choke tweak for your speakers.
No RF problems but the tweeters are a little too bright due to my room. I may have implied that the sound is harsh when I meant a little fatiguing on some recordings along with some sibilant sound. The AQ's tame this a little, probably because they have a higher capacitance than the BJC's which have a very low capacitance. The resistors attenuate the tweeters by 1-2 dB which greatly helps. I found using a lower ohm resistor helps with this but does not change the overall sound.
