I noticed an improvement when going to hospital grade outlets. Even commercial grade 20 amp outlets at 3.50 each are much better than stock, as noted above, much better grip and greater contact area.
I would certainly love it if someone could explain to me the difference between a good hospital grade outlet at 15.00 (from your local electral supply house) and PS Audio's and the other "audiophile" grade 50.00 ones. I can't see any rational at all in spending that much money on an outlet. But maybe someone out there as done a direct comparison and could enlighten us. Remember, when buying the hospital grade receptacle, DON'T tell them you're an audiophile :)
To me money would be much better spent by installing a 20 amp dedicated circuit or two. Cost for materials, including 2 hospital grade outlets, for a 50' run is about 60-70 bucks each circuit, and that is using 10 gauge romex instead of 12 gauge. No part of any system is greater than its weakest link. It is more important to look at the complete circuit and all materials used than any one single part.
