Stynergistic Research FEQ X 4

Just finished outfitting my small listening space (3rd bedroom about 11' x 12') with Synergistic Research's HFT's (full spectrum using the standard HFT's, 2.0's and X's) and now have the FEQ x 4 in place behind my speakers. Since these devices deal with  ambient RFI and EMI fields I was just wondering if there's any such thing as a break in period or is what I hear at the beginning as good as I can expect? That's not to say I'm not impressed with what I'm hearing because the sound stage is now more holographic (3D) than I've ever heard it before. The noise floor has been lowered so I hear more. It lives up to the promise of making my speakers disappear. Just asking what others have experienced with their set up.
