You don't say if you rent or own, but if you own I would suggest installing a 20A dedicated line to your service panel and locating a new duplex closer to your electronics.
If you don't want to install a 20A dedicated circuit, then at least have a new duplex installed closer to your electronics. The cost will be surprisingly low compared to what we typically spend on power products.
Doing this will eliminate the long 25' extension cord and allow you to plug your components into a power conditioner/surge suppressor closer to the outlet.
