SR-Z1 Wall Outlet

The high-quality outlet I’m most familiar with is Shunyata Research’s SR-Z1, widely available for ca $95. Unless you’re an experienced home handyman, hiring a licensed electrician to do the changeover pays dividends in peace of mind… Unless you’ve replaced the wall outlet that your system plugs into within the past few years, that outlet is probably long past due for replacement — especially if you can look inside the outlet and see drops of dried wall paint. Even if the outlet hasn’t been painted over, upgrading to a heavy-duty, cryogenically processed outlet will remove major bottlenecks in both the outlet and its connections to the house wiring.)
