Least expensive plug-in power conditioner that works

Thanks all again for your comments on the topic.  I am intrigued by the Puron AC Power Conditioner - very good user and reviewer impressions. I may buy one and compare to Shunyata Venom Defender and ifi iPurifier in most critical site to see which works best for me.  Will report back.

Check the other used equipment site for sale items.

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.
