Upgrading wall outlets

Let's break this down to a basic, black and white level first. The shades of gray can wait.

Will you spend thousands, even tens of thousands of dollars for an amp, speakers, etc., then plug it all into a 20 year old receptacle that is so worn out that it can barely keep the stock plug from falling out?

Saying, "but that's different" is an admission that receptacles make a difference. Saying "of course; why not?" means looking at that sagging cord and wondering and occasionally pushing the plug back in. Or not. Why would you if it doesn't matter?

Which side of the fence are you on? No sitting in the middle; it won't support you. It's too tall to straddle, too.

Whatcha gonna do?

I can tell you - I changed fancy Leviton plugs to Porter Ports this week, and it made a very big difference for the better. The system is cleaner and clearer throughout,lyrics are much easier to understand, instruments I never knew were there, are clearly displayed. Porterports are certainly worth the asking price.

I've had very good results using Oyaide SWO-GX and Furutech gold plated. I did not have a good experience with some other aftermarket outlets and eventually took those out of the system.
My experimentation was done mostly with my CDP.

I installed Synergistic Research Teslaplex outlets on all three of my dedicated lines and the difference was huge! There is something to be said about there Quantum Tunneling process.

Now that the smoke has cleared from this thread, I'll tell you that I just ordered a Porter Port and will be running a dedicated circuit this weekend. Regardless of the argument, when someone says they noticed a very big improvement, I'm willing to spend $40 plus the cost of the wire (that I already have and purchased when gas was still cheap a few years ago) to find out for myself. My current outlet is old enough to be considered an antique and quite possibly could be 50 years old. If anyone's going to notice a difference, it's going to be me. I'll let you guys know in a week or two how it goes.
