Maestro faceplate - does it make a difference?

No.  Don't waste your $$ on snake oil.

If you DO have a problem, address power cables to your DAC first & then an AC power converter (transformer) such as a used Topaz.

a search on here will be revealing

Its not the faceplate, but the Maestro outlet that makes the difference.  Just use a 29c plastic Home Depot faceplate

Just use any decent $10 to $15 outlet - Hubbell and others make good solid ones.

You want a solid connection (for the amp) - nothing else matters at an AC power outlet

randy-11:  have you actually tried a Maestro outlet in comparison to a Hubbell in order to speak so authoritatively?  Or are you speaking from speculation based upon assumed principles?

Or are you speaking from speculation based upon assumed principles?

That's our Randy!!!

I would buy a Porter Port before I bought Maestro duplex receptacle.

The Maestro starts out as a Cooper BR20 duplex outlet. At Lowe’s, $3.47

OP,

A non breakable nylon duplex plate will work just fine.

jubrip - there is no point in wasting time on things that can only work by confirmation bias, not by any known laws of physic or electronics

better to buy some ball bearings, cups and damped tiles to sit your components on...

Some more data to consider:
I built a power box with 6 outlets and put a fancy stainless steel faceplate on it so it would look nice. I then decided to try a lightweight nylon faceplate after getting rid of ferrous materials in my power cords.. the nylon faceplate definitely sounds better. 

As for which faceplate you should get.. that's beyond my paygrade

Just to mix things up a little the ones I sell are actually resonantors. I know what you're thinking - why would you want to put something that resonates there?  Thus, you can employ them on UNUSED outlets as well as outlets for audio devices AND outlets for non-audio devices with good results.

Or maybe Geoff buys his ceramic wall plates on Amazon https://images-na.ssl-images-amazon.com/images/I/41vDumcXTWL._SX425_.jpg for $3.82 and offers them up to audiophiles that visit here or his website for $30.00. If I were to use these plates I would upgrade and  use a non ferrous brass machine screw for $.59.. Tom

Tom, are you high? My audiophile outlet covers are treated a number of ways. Sorry but I can't actually tell you how. Then I'd have to kill you. Do you really think I have a kiln here and produce my own ceramic duplex covers? That's special.

Most treatments are $5.00 per pound less shipping to and from. How many of these = 1 lb. ? Tom

Tom, you really are high, aren’t you? What on Earth are you going on about? This particular conversation highlights the differences between high end audio and pro audio. 

I use the same treatments in pro audio products and home audio materials and products. Material treatments are beneficial to most everything even if the product's raw cost is $3.82. Forgot about the $.59 brass screw. That should be treated as well. Tom 

I may be slow but I’m ahead of you, Tom. You have undoubtedly only scratched the surface of materials treatment. I don’t know why you insist on thinking you know what I’m referring to. When you assume something you make a fool out of me and Uma Thurman. Can I suggest you start thinking outside the box? 🕋 A journey of a thousand miles starts with just one step. 🚶

Like your ahead on the understanding of interfering energy in all solids that vibrate. Your still stuck in the box of sand and silt. Tom

"Upon graduation from Acme Audio Engineering school today many of you will go on to do great things. The rest of you will be in pro audio."

(recently copied from another thread)

Now this:

“This particular conversation highlights the differences between high end audio and pro audio.”

I personally earned a great living in professional audio and must reply to the attempted insults listed above which then begs the questions...

If we did NOT have ‘professional sound’ who then would be responsible for Geoffrey even being here?

Who came first? The recording engineer or Geoffrey C Kait?

Oh well, mistakes do happen.

I would rather be working in “Professional” sound in comparison to becoming a disgruntled space agency retiree consistently shilling his products on the AudioGon forums.

To the OP: We purchase products and parts for our engineered sound rooms from vendors with return and paid “in-full” refund policies. Some vendors who deeply believe in their products offer to pay for return freight as well - just ask them. Auditions will provide you the audible answer without opinions and/or insulting personalities getting involved.

You two knuckleheads seem to be ignoring the fact that I’m the one with the degree in theoretical physics. I’m the one with courses in statistical thermodynamics and nuclear physics. That I’m the one with courses you’ve never even heard of, you know, like indeterminate structures and theoretical propulsion. Can I respectfully suggest you two guys march yourselves 🏃🏃 right down to whatever Podunk school you went to, assuming you even went to school, which I actually doubt, and demand your money back? Which probably isn’t that much money to begin with anyway, maybe a hundred bucks. Whatever kind of education, Phys. Ed. or whatever you get from the back of a matchbook cover. If you’re getting upset by my comparison of pro audio and high end audio that would be, uh, your problem.

Geoff,
Much of what has grown out of the movie theater Professional installations of the 1930’s ..Western Electric and RCA are still being pursued for their simple magic and are being copied even today for their use in high end audio system products. You should remember those installations as you are of the same era though not as significant. Tom

I hate to judge too hastily but perhaps I need to hire a translator to translate my posts. Jea48, what was it about ceramic duplex outlet covers and resonators that you didn’t understand? Why all the angst? Don't get all strung out on me. It’s not rocket science. 🚀

I replaced one PortaPort with Maestro.....after which they all got replaced.   Maestro on my system wounded open effortless, clear, etc., etc, etc,

I really like my maestro outlet. Made a very nice noticeable improvement all across the board.

jea48
So you have no idea how it sounds..... You could have just said that....

Huh? Whoa! What are you talking about? Try to stay in the saddle. 🏇
.

anyone advocating spendy outlets - much less covers - had better be able to offer some electronics insight into how they could possibly improve SQ

and no, confirmation bias is not a good reason to buy snake oil

Jea48, did you forget to take your smart pills this morning? You’re so emotional. I wonder what’s eating Gilbert Grape?😱 I apologize in advance if English is your second language. It's possible there is a language barrier, although I doubt it.

What on Earth are you going on about, now? Maybe you need a time out. 🛌

Robert, you shouldn't get yourself all wound up. You're liable to break your mainspring. 

You can buy one just like it..though untreated from Amazon..for less than $4.00. How would know its treated unless you had 2 that were untreated and you sent 1 off yourself for treatment and then compare. Tom

jea48, please save the drama for your mama. Shouldn't you be standing out on a ledge somewhere?

Whoa! What! Wow! You’re quite the genius when it comes to pointing out the obvious. Good job, Skippy. Did you learn that in Acme Audio Engineering School? 😀

Skippy as in peanut butter?  Just pointing out the obvious about price gouging..25 of these plates may weigh 1lb..5$  for treatment and $15 for roundy round shipping. Tom

So Geoff at a 25 piece qty. you will have a cost per piece of about $5..per unit...nice profit on a $30.ticket. Good job ..Worst you have to do is to drive to the post office..if your allowed or maybe you call for pickup. Then you will have done nothing. Tom

Tom, don't take this the wrong way but are you crazy?

For one it is gross margin $$ and for the rest ..the consumers it is just gross..Tom

Tom, you need to get your minds up out of the gutter. I direct that comment to both of you. 

Yes I use both sides of my brain or as you have pointed out ..both of me. Tom

Tom, roses are red, violets are blue, you’re a schizophrenic and so are you. 👯

Geoff
You always change the subject when the negative is of you..Tell us more about the form and function of the wall plates you buy from Amazon and then resell. Other than yourself who do these wall plates benefit? Tom

Tom, you’re a sick little monkey. Is your handler hiding? I don’t blame him.

Hi, Tom, about time for another nice long cold shower, eh mate?

jea48
Do you sell a wall duplex outlet cover on your website?

>>>>3 guesses. The first two don’t count.

jea48
Have you ever tested it for how it impacts the sound of an audio system?

>>>>3 guesses. The first two don’t count.

For those among us who may wish to use their own eyes for comparison to the photo in the link above you could possibly venture to Geoff’s own site as he wishes you should do. Notice the change of photo profile and the stunning and rich backround of rich Corinthian leather..$30.00..compare to the Amazon link below.. Leather in photo not included. http://machinadynamica.com/Tru_Tone_Cover.jpg

For comparison here is a photo of a strikingly similar ceramic ac outlet cover sold on Amazon for $3.82. Forgo the faux leather and upgrade at a low cost with the use of a non ferrous brass screw ( 59 cents) instead of what is supplied.

Tom, have you completely lost your mind? Didn't you get the memo, all duplex outlets look approximately the same? Duh? Write your congressman or contact Better Business Bureau of your panties are still in a twist. 👙

Jea48, I’ll leave you to your thoughts. It's pretty clear you’re following the wrong, you know....
