It's tough to say whether a power conditioner will make an impact in a different system, and if so how big that impact might be. Over the years I've lived in several homes and each one reacted differently to power conditioners - in some cases it made a drastic improvement, in other cases little or no difference.
Beyond that, I've even had different houses which reacted better to different types of power conditioning. One home did best with regenerated power (I used PurePower but PS Audio made conceptually similar models at the time), another liked the more straight forward filtering types (Audience, Puritan Labs), and my current home favors balanced power (Bryston, Furman, Equitech).
Unfortunately that means the answer likely involves trying things for yourself and seeing what works in your home.
