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

Justubes2, that’s great how you’ve arranged units. I did the same thing in my PS Audio: however, it had the Teslaplex SE and an FIM outlet. I couldn’t get both units to fit in there: the Furutech is larger than a standard outlet. So, I could put in either a Texlaplex SE or A Furutech. I’ll have to retry it, since I also have a Power Plant P300 and see if I did something wrong the first time. The sides of the units were nearly touching in my unit.
In any case, thanks for the expository on your experience. And just to clarify, I wasn’t asking for brands: my phrasing was clumsy there. I meant it to be a query about whether or not you’d tried it with ss AND also tubes or one more than the other.
I did finally put everything on the Shunyata Venom PS8, plugged first into Synergistic and then the Furutech, but I’ll have to listen longer, since, with Shunyata, moving the power cord (or anything else) dooms immediate critical listening. I’ve found the system to settle down after around 2-3 hours, and had company, so my listening time was limited. Also, I had a Nordost Frey on the CD player, so it wasn’t a "pure setup," although I have enough Shunyata power cords to power the entire system. The only observation I had was that on the Rolling Stones Rhino release on "Gimme Shelter," Merry Clayton’s words were clearer, but the sound was slightly artificial. Now, keep in mind that the PS8 has only been my system for 8 days, so I’ll have to wait longer, but putting it on the Furutech did not make it sound better, ALTHOUGH, Mick Jagger’s voice certainly gained a veracity that was not due to dynamic intensity, but a more full representation of his voice as I’ve heard it (on say, vinyl). What I think you would call "organic." I find all this fascinating and don’t mind the experimentation at all. I’ll wait another week, when the PS8 has nearly 400 hours on it, although Shunyata says 200 hours is enough (I’ve never had the pleasure of a Shunyata cord - or anything else Shunyata - being at its best at 200 hours (speaker cable being the only other Shunyata products I’ve had). Never the interconnect, except for the first generation Aries, which benefited their power cords, which were slightly recesssive in the upper midrange, where the Aries was just slightly bright, so it made for a ...synergistic match, as do most designers when they voice units. Dave Wilson used to use Rowland to voice the WATTS, Transparent used Wilsons’ Grand Slamms for their cables, etc. Everyone is gong to have a certain voicing because they have to use another manufacturer’s preamp, amp speaker, turntable or CD player to create THEIR product, so if you know say, CJ uses Nola, or Magico speakers (or CJ’s own speaker), you can reasonably assure yourself that part of the sound of the CJ comes from the product the’ve used in its creation. Of course, some manufacturers use several different amps, preamps, etc in the creation of their product, so yet another variable is thrown into the monkey wrench works, as it were.

I should mention that I also noticed that the Synergistic did an about-face shortly after my Nov. 3 post, and that the guitars seemed a bit dull again, meaning transients as the most obvious change, and then, the image placement in the depth field collapsed slightly again. I thought perhaps the strip the microwave (in the kitchen) was plugged into wasn’t turned off (dedicated circuit or no, both here in CT and in my apartment when I lived in San Francisco, I could easily tell when the microwave was powered on. And I demonstrated in an acquaintance’s house, someone with an excellent High End system, that the microwave could reliably be identified as "on" or "off" and they heard it within a minute (I was wathcing them out of the corner of my eye and I saw them cock their heads as they realized that the sonics were noticeably different, which they confirmed after the cut finished). The microwave, by the way, was NOT on, so I couldn’t blame the change on that. I just thought "more break-in time."
So, I hear exactly what you’re saying and I agree. What I’ll have to do is try to put both an NCF AND another "Black" into the PS Audio (meaning, replace the Teslaplex SE that's in there) to see the results. I will say that, so far, although I like the Venom, I haven’t heard it - other than to move the presentation closer to my listening seat - demonstrate an unparalleled improvement over the P300, but I’m willing to wait longer. Right now, it has exactly 224 hours on it and counting. But, neither is it easily distinguishable from the P300. Yet. So, I could be hearing the "Black" outlet or it could be the Shunyata, and it’s too soon to know which, without more time.
In any case, I appreciate your extremely thorough analysis and comments and I think other will benefit from reading your post as well. Thank you.

Gbmcleod,

The teslaplex se will not fit together with a GTX, but the narrow Black (of Non SE) which combo i was using previously could. 2 GTX or 2 Teslaplex SE's will not fit the P300 in this combination.

I especially value the cleanwave of the p300 which does clear the sound a bit, much like running a demag disc.

It's been a pleasure engaging in meaningful discussions with you and it very constructive in our tweaking quest.

My other black outlet is installed, yes, a calmer or organised sound with a tad more rigid sound, still good and does better slightly the SE it replaces.

This control of sounds appears to also limit the high frequency brilliance and any residual bloom in the mid regions and bass, though it does go deeper. Please read brilliance  that this is not glare, harshness , hardness or tinnitus effect. I may be fortunate to not have any traces of these negative artifiacts in my system now.

As from a fresh memory. this brilliance in treble and high frequencies even compared to the SE and even more so to the GTX or GTX(NCF) could be considered as a downfall, though still sound good and pleasing.

The changes introducing another black outlet and fuse does not make for a large change, it's improvements now, i would consider more a change sonically. Do not that this is 2nd black outlet including fuses.

I would not fret over leaving the SE or have any real preference over the black now.

It goes for the fuses and the red fuse can and will probably stay. Incidentally, i have intentionally compared these 2 fuse in the wrong orientation (which i prefer actually sound more musical over the hyped up sound i was getting in the "correct" position which though technically better in audiophile terms was fatiguing and less musical to me.

As with equipment, the voicing or match has now to be determined by the user and tedious comparisions of various equipment  and tweaks.

i do look forward to your further findings, so as that may provide me with a 2nd opinion with these outlets and also re-evaluate which areas may be lacking and re-optimize the combinations of outlets.

To hasten the burn-in process and settling time in the systems, i have found using the cleanwave of the p300 (Multiwave set) together with a burn in disc afther reintroducing any component does seem to normalise the sound thereafter rather quickly especially set to repeat overnight or even a shorter time frame.

Jim:
That’s intriguing, but let me think that over. I am not sure that I want to pull the outlet out, as it’s in a tight place with a bookcase in front of it. And if I decide to do it, no need for you to get the outlet: Lowe’s is nearby and it would be intriguing - if I have the time to test the outlet - to do it.
Justubes: remind me which setting is the "clean wave" as I can’t find my PS Audio owner’s manual (I know it’s online, so I’ll also look for it there). I have traditionally used the setting on PS 2 and 120. What is your preferred listening settings for normal listening?
I was just listening to Joplin again. An interesting experience, but not sure it’s a valid one, since I had to plug the power cord into the P300 on a Teslaplex SE outlet, and, of course, the NCF at the wall. I heard the "organic" nature you refer to, but tonight, I plugged the power cord directly into the SR Black again. I noticed that the throat/chest region of Joplin’s voice was more fully developed on the Black outlet, but then, that’s going directly into the wall, whereas, the other way, I have no way to put it directly into the wall: the outlet would require a 4 meter power cord (waaaay too expensive). Just listening for the emotiveness, I’d have to say going directly into the Black is preferable to going into the SE outlet on the P300. I could "place" Joplin’s voice more clearly and hear "into" the center of her pitch better with the Black. Again, not a fair "controlled" experiment, but just speaking from a "feeling" point of view, I prefer the Black to the P300/Tesla SE/GTX NCF-at-the-wall combo, w which surprised me, since the last test with the Shunyata power distributor and the P300 was a ’wash’ as far as I could tell.
I don’t find the Black to have that somewhat highlighted presence region that the SE does, and while I agree that the NCF sounded more organic, I didn’t detect that Joplin soulfulness was as pronounced as it demonstrably is with the straight-into-the-wall Black outlet. When the PS8 is fully broken in, the cord will be long enough to test both outlets, but for now, I prefer listening NOT thru the P300 for the amplifier (the CD player is still plugged into the Tesla SE outlet in the P300 and, again, the NCF at the wall. Perhaps the Tesla SE is the weak link here and influencing the sound unfairly. Don't know yet. But the amp going into the Black outlet on its own dedicated circuit,  is decidedly more soulful, and that went for the Rolling Stones, Rick James’ CD, Joplin, Nina Simone and Ella. I’d agree that there is a very slight loss of liquidity, but it (the Black) is not what I’d call ’dry-sounding’ either. But I clearly hear the organic nature of the NCF. Perhaps on something other than vocalists, it shines, but the Black seems to allow the pitch center of a mezzo-soprano (which is where Joplin and Ella both sing, although in different ranges, and Joplin, from what I read, had a wider range [3 octaves] than Ella) to sound "pure". I’m speaking purely of vocalists, though. I would say the Black is more ’exciting’ in this way, although, knowing a decent amount about Black singers (family members who sing, and church and the community), I’d say the Black outlet favors - no pun intended - Black singers, both male and female, easily as good as the NCF. Don’t know why, but the ’grittiness’ and soulfulness factor is in full swing in this genre of music. I’ll have to play some Etta James and Aretha to confirm this, but that’s how it sounds so far.

Jtubes, incidentally - and I meant to say this earlier - I also use a SR Red fuse in the P300. I bought a Black fuse, but actually didn’t like it in that application. it’s interesting we both use the Red in the P300, or at least that’s what I thought you indicated you have in there. If so, that’s pretty fascinating we both heard the SR Red as the best fuse for the P300.
And, could you clarify something? You referred to the "narrow Black" which I took to mean  Synergistic's outlet. Is that what you meant? If so, it sounds like you can put both an NCF and a UEF Black into the P300. So, is your testing with the NCF at the wall, and also installed in the P300, with a UEF Black as the second outlet? Sorry if I'm being slow here: it's late and as you can see from the 'time' post, it's late. Zzzzzzzzzzz time is approaching...
