Electrostatic speakers and power conditioning

Hi,

Does anyone have any opinions as to whether electrostatic speakers can benefit by connecting the AC adaptors to a power conditioner or directly to the wall. I've heard that a power conditioner can shorten the life of the speakers as they would not be getting full power. If possible I would connect the speaker straight into the wall but the number of outlets may be limited in which case I may look into the Eichmann strip which is a bare bones product.

Thanks.
