Is the Maestro AC outlet basically a cryo'd Cooper BR20 found at Lowes for $3.47?

I use and like the Porter Port outlets. I started to use them when Albert started up the sale years ago. For the price I think they are hard to beat. With that said, I find the Furutech GTX-D (R) outlets to sound superior in both of my systems, I use 5 of the Furutech GTX-D(R) outlets along with some Porter Port outlets. The sound is more dynamic, three dimensional, with more detail and bigger bass. The down side is the price and the "LONG" break in time. Sometimes up to 300 hours! Luckily I have and used my Audiodharma Cable Cooker to break in the outlets and I did not have to put up with the misery that so many others had to listen to during break-in. There is a lengthy discussion in the Audiogon Forum regarding the Furutech GTX-D(R) outlet and other outlets.
These might be the two Forums I was thinking of if you have the time and patients to read through it all. There really is some good information here:

Because of the expensice I purchased them one at a time or two at a time and daisy chained a pair together.

I don’t own the outlet, however I know from using the SR Black fuses that there is a long break in process.
I’m glad you are enjoying the outlet and that it has improved the sound quality of your music.
BTW; very nice review ;-)!
