Audioquest DBS vs Synergistic Research Tesla?

I prefer synergistic research hands down, I've never tried the sky or whatever the top audioquest speaker cable is, or the top Tesla SR cables, but in terms of whether DBS or Active shielding is better, Synergistic wins easily. I owned generation 1 Alpha Quad X2 active speaker cables, and then I owned Panther DBS 2m XLRs that went from my dac into active speakers.

I've owned cables with both technologies. If you take the battery out of the DBS thing, the difference is subtle. (at least in the panther I owned with the 36v or 72v dbs, cant remember which). If you unplug the syn's active shielding, the there is a dramatic difference in soundstage and imaging. One final difference in how these 2 things work, audioquest says you'll never need to replace the DBS battery, the synergistic research active shielding requires an AC plug, they are very different approaches and not comparable imo.
