I have a couple of these for my stereo:
"Belkin Power Strip Surge Protector - 6 Rotating AC Multiple Outlets, Flat Pivot Plug - Heavy Duty Wall Outlet Extender for Home, Office, Travel, Computer Desktop & Phone Charging Brick (1,080 Joules)"
They convert a dual gang plug into a six outlet with protection.
And one of these for my AV system:
"Belkin Surge Protector Power Strip w/ 8 Rotating & 4 Standard Outlets - 8ft Sturdy Extension Cord w/ Flat Pivot Plug for Home, Office, Travel, Desktop & Charging Brick - 4320 Joules of Protection"
This one has enough outlets for all the AV gear.
Tight plugs, good construction. Good luck!
Happy listening.
