Least expensive plug-in power conditioner that works

I use a Welborne Labs, Gatekeeper. So much written (mostly negative) about this company but if you have one of their amps, power conditioners/surge protection, etc you know they are each quality pieces. I plug some fairly expensive gear into the Gatekeeper and it does the job. Prob find one used for a couple of hundo. Just my opinion...

The cheapest thing to do is put a dedicated powerline into the wall

That was my starting place as my main system is in a purpose built room with a dedicated 20amp circuit breaker and 10 AWG power supply line.  For years I followed the logic that connecting my AVR directly to the wall would provide the best performance.  I recently connected it to the strip with the Venom Defender that supported all my other gear and that made a very significant positive improvement in the overall sound of my system.  Why I am interested in competing products that might work better, and given I want to try placing them with my modem in another room and my TV in the same room but served but a different outlet.

Bottom line, the Defender is a solid product, just wondering if there are similar products that might work better.

Hi, I went through this with my system.  Look at the specs. It's quiet right?

So, first I bought DX Engineering EMI RFI filters for the ethernet line.  One on each end $50.  I bought these as a trial to prove to myself that this conditioning stuff works.  Then I would buy something more audiophile.  About the same time, I got a new modem, still coax but a linear power supply.  The speakers sounded better.  The I bought a Furman Elite 15i.   Plugged all my equipment into it.  Around the house I plugged all the chargers, dimmers, etc into a furman ss6b.  I have 3 of those.  I have less than $500 invested.  I am a firm believer the better you keep noise out of your streaming system.  The sound is much better: Details, 3d and wide soundstage, bass i never knew could be so good, much more natural sounding.
