I second @audphile1 and the suggestion to simply a change your duplex box to a quad box. Use whatever fancy (or not) outlets you want. Depending on your current draw needs, service box capacity, and access, you could even run two dedicated lines to the two outlets, or not. Either way, the most practical and least invasive(sonically) solution, IMO. Good luck.

I have a dedicated 20 circuit. The problem is that it’s only a duplex box and since I went back to mono blocks, I need more outlets.
Does someone sell a high ish end cord with a good duplex box or a good quad box on the end? It’s mostly going to be used for power amps, so I don’t need any conditioning.
Thanks all.
