Unfiltered Power Bars

I use a Synergistic Research QLS 6 line strip.  There is a used one for sale out there for $250 on another site.

You can't go wrong with any of the models from Isotek.

I have been happy with this unit from Emotiva:

I have to agree with @tomic601 with the Furman for the digital and @nonoise with the Cullen for non filtered, use both in two systems and they are both very price effective. Enjoy the music

I recently bought a used Audience AR1p and plugged my Wiremold strip into it and it generated a much more open and dynamic soundstage. I’d highly recommend stretching your wallet and pursuing this while still using your Wiremold for any other necessary outlets...

And if it doesn’t produce significant sonic benefits, just resell it.  That’s what I did, except I kept my AR1p and am thrilled with the benefits in my HeadFi rig versus plugging into the wall.  And you can do this almost risk free as Audience power conditioners have a very fluid used market.  Hope this helps, and best of luck.
