I have a few which do not have active shielding. I have tried a few which did. Needless to say, results will vary, though I found no ostensive value to active shielding when it came to sonic improvements over those of most other power cords which did not use an energized network.
The aforementioned experiences occurred while I was using actively shielded IC as a main, and active shielded speaker wires. Presently I use but two sets of actively shielded cables, and both are speaker cables. Both are Synergistic Research but different models and lengths.
The active power cables I tried were as well, sR. this was some time back and the tech may have and likely has changed. Improved? Dunno.
The usual answer on these topics sits wsquarely on the Ops shoulders. They will have to give some a try to find out for themselves in their own system, location, etc. to be certain.
Best of luck
