Line Conditioner

Do any of you use a power conditioner, like the Furman AC-215A https://www.amazon.com/dp/B003PJ6NPO?tag=amz-mkt-chr-us-20&ascsubtag=1ba00-01000-a0049-win10-other-nomod-us000-pcomp-feature-pcomp-wm-3-wm-1-wm-4&ref=aa_pcomp with their KEF LS50 Wireless? Any thoughts about whether doing so would be worthwhile?

Thanks!
