I need a extension cord with

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.


What’s your budget? I have build really, really good ones with very thick aluminum chassis and SR Purple duplexes wired internally with DH Labs Red Wave cable.

If your budget is leaner than $500, you can also consider this from Pangea and get a good 20A cable to go with it. 


Depending on the wall construction of your listening environment, an electrician might be able to give you a quad box or added receptacles for not a ton of money. Maybe an hour or two of labor and minimal parts cost, assuming you use hospital-grade but not "audiophile" receptacles.
