Audiophile AC Outlets

I installed an Oyaide R1 about 15-18 yrs ago and haven't looked back. Tried an Arrow Hart before that. It was an improvement over the cheap outlets I had previous. But the R1 was a big improvement. 

Installing a 20A or 30A dedicated line may be as beneficial as an audiophile duplex. Highly recommended if you have easy access to route the cable. If you drill the holes and pull the cable yourself, as well as supply your audiophile duplex and the correct circuit breaker for your brand of breaker box, an electrician should be able to complete the job in less than an hour. Or you can study YouTubes and do it yourself. Your local codes may allow for installation of a gang box directly on the floor (rather than in the wall) which makes the job easier and you may find upward facing outlets much easier to use than horizontal ones.

I've gotten better results with the Synergistic Blue and Black outlets over the Shunyata cryo and the PS Audio Power Port outlets. I'm tempted to try their Orange outlets (the Orange fuses are great), but in my setup, getting to my two dedicated outlets is a real PITA...

I have 2 20amp cheap outlets and older oyaide and furutech gtx-d (R). Each step up is worthwhile. I'm considering SR Orange outlet in hopes of gaining a little more mid-upper bass energy and clarity. Can anyone comment on their relative EQ compared to furutech rhodium? Has anyone compared maestro to SR blue or orange?
