Product review (5 stars): NOW MY AMP GOES TO 11
I bought these to use when running dedicated circuits for my stereo. I couldn't imagine spending $100 or more for "audio grade" receptacles so i went with the Levitons and have no complaints. Of course hey aren't going work miracles for any stereo but i doubt the expensive ones will either.  At the price these would be hard to beat regardless of what you intend to plug into them. They have a nice sturdy feel during installation where I usually feel like I might break a standard receptacle.  Also with standard outlets the heavy power cables tent to sag.  These hold them in place perfectly and I never worry about loose connections.
