power cord or power conditioner?

I would have to say a good power conditioner for the reason that all of your components will benefit from the clean power. That said, if you are thinking about a PS audio ( I recently purchased this model) to get the best out of it you will have to buy a good power cord. Don't get me wrong it will improve the system with the stock cord but does require a quality cord to get the most out of it.

Best of luck!

Do you really need a power conditioner?

I will be the first to admit how big a difference the PS Power Plant has made. I was using an older Chang Lightspeed filter before. The sonic benefit was as if I changed a major component. Better and more defined bass and a bigger more articulated sound stage.

It took a long time before I was willing to spend that kind of money on a power cord and power re-generator. My dealer who I do trust to always steer me in the right direction assured me it was the move to make.
