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

I have been using Furutech for years now before they became 'force' in United States. I started with Hubbell outlets, then switched to FPX (G) and finally to GTX-D (R) on all of my wall outlets, power conditioners and FI-28(R) on my power cords. IMO, every tweak has a cumulative effects on the sound.  The overall synergy of outlets with plugs is simply outstanding.  

I was able to achieve ultra smooth vocals at higher volume, better dynamics, tighter base and excellent tonal balance with Furutech's in my rig. 

I agree it's a expensive upgrade but guys it's worth every penny. The outlets and plugs build quality is phenomenal. 

I won't be trading up to NCF for a good while. 

I just received the Furutech GTX-D(R) on Saturday and have not had time to install it yet.  After I do, I will come back and post my impressions.  I have to agree with lalitk,

The outlets and plugs build quality is phenomenal.

I use their plugs, rca and xlr connectors on cables I make and the build quality of the connectors is excellent.  The build quality of their wire is also very good as I have used their bulk IC, speaker and PC wire.  I have been very happy with the Porter Ports but I was able to purchase the  GTX-D(R) as a "new, open box" item at a very good price so I thought I would see what all the fuss is about.

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:

I was told by someone in the industry that I trust, Maestro is just a cryo'd hospital grade outlet.  

Eventually I replaced all my Maestro outlets with Furutech GTX-D(R) and it was NO contest.   Furutech is much much superior.
