World's BEST AC Outlets.....MAESRTO AC Outlets ???

No, I haven't tried one. I use hospital grade outlets, myself. For $79, I should hope the vendor would include some sort of impartial third-party test results showing verifiable improvements over standard grade outlets... maybe lower resistance, lower audio distortion, cleaner AC sine wave shape, etc... anything to prove these are actually "better" and worth that kind of coin.

Oh come on. What am I supposed to think unless the measurements tell me what they sound like???

:banana:

Ok, seriously, I'd like to see a comparison between other "high end" rivals like Furutech, etc. And even hospital grade plugs (that I can't seem to find around here - unless they are orange).

I'm using Porter Port outlets right now and these are one of the best that you can buy. I was looking over on audio asylum forum and some say the Maestro outlet is a lot better than the Porter Port outlets... http://www.audioasylum.com/audio/tweaks/bbs.html
 
Wow. $79 for an AC outlet. And I bet there are other much more expensive ones out there. I can understand the "hospital grade" in a hospital where you have oxygen in use and a spark could cause a fire.

Beginning to really appreciate my $2.99 20A Home Depot Leviton outlets! This one seems to conduct electricity perfectly well to my stereo, no measureable voltage drop, it doesn't get even the slightest bit warm, i.e., no resistance, can't measure any increase in temperature of the outlet with a laser thermometer after playing all day, I've tested it. Seems to me if there is a diffrerence heard, there might be a problem with the old outlet not making good connection, or the power supply in the equipment has weak or underrated components that can't keep above the full power demand or stay fully charged. :scratch2:
 
I would not mind having a in-wall UPS with surge suppressor. $79 for an outlet, does it really make a difference?

Amen, brother!
 
I'm trying to figure out if this is a hoax? I have electrostats that need AC, I use Crown dc300a's to drive them.

For AC I use one APC 1000ma UPS for the Crowns, and one for the two KLH 9's the Preamp, CD players and the Television and DVR.

Since beginning to read this thread I have also used a lazer thermometer, and can't find any difference between the wall and the various power cables. The UPS's do operate a couple of degree's above ambient.

I cannot figure out how a properly working AC socket would affect the audio. Maybe an old rusty one....... :thumbsdn:

Exactly. If you take apart a run-of-the-mill 99cent outlet, you'll find brass contacts that touch the plug blades maybe at one or two points. Expensive outlets or hospital grade ones have larger contacts that make better contact with the plug blades. The contacts can be made of any number of materials that conduct electricity better and with lower resistance.

I did try an non-audio experiment once. I have an outlet in this room where I regularly plug in a 1200W electric baseboard heater. When I used a cheapie outlet, the plug and wire on the heater, as well as the face of the outlet, got real dang warm. :nono: I'm talking too hot to even touch the plug. I replaced the outlet with a hospital grade type and ran the heater. MUCH cooler operation, even after extended periods of time. Lower resistance, better current flow. If a heater works better with a good outlet (safer, too), then it isn't too much of a stretch to figure that audio equipment would, to some degree, get fed better.

That's nice, but just because your budget AC outlet works and measures fine doesn't mean there would be no improvements with something better, regardless of whether or not you understand how it could work or know how to measure what's being heard.

I almost got in trouble by writing something that would be against the TOL forum rules. Suffice to say I agree with you.
 
From what I've read, there is a 30 day home trial with this product. If some of you want to bash it, why not get the home trial, plug it in, listen and then bash it all you want. It may or may not make a significant or insignificant difference in your gear but the outlets I have tried sure did in my gear, some not so good and some were quite an upgrade.

I have been running Oyaide R1 for the past couple of years and if the Maestro can beat it, I figure this is 79$ well spent. There may be hospital (white or red) that you may feel are a better bargain. I'll vouch for the red Hubble as a fantastic bang for the buck product. It should suit most people's needs.

How in the world can you comment negatively on something you've never ever tried?

Yes the 2.99$ Leviton may be the real deal and a world beater, I have no qualms with this, it may be enough for most (including myself if I had the chance to try 1). There have always been gems around.

AC outlets (copper) can become oxidized over time and putting in a new outlet will rid the copper of this oxidation which should yield an improvement in overall sound. You can reinstall your old outlet and the same improvements could also be heard.

There is a method to testing and debating issues. It shouldn't always be a show of outrage or ignorance. Try cleaning up your outlets and listen to your gear before and after, then make all the changes you want or stay put, at least you'll know why you stand where you stand. Tests should always be conducted on clean copper wiring. Then and only then can we formulate opinions on gear.

What can be accountable for differences in sound are the materials that the electrons must flow through unless we all believe that aluminum, silver, copper and gold all sound the same. I for one think that all materials may colour (corrupt may be truer) the incoming signal. There is no perfect straight wire that is perfectly neutral adding nothing at all, not to my knowledge. Everything matters and all components of an outlet may affect its performance.

Regular outlets loosen up in time and the prongs (from your a/c plug) may sway in the outlets to the line frequency, tell me this doesn't hamper ultimate performance. You kinda get what you pay for. When your mains cable has remained oxidized for years, cleaning it up is the cheapest tweak that I know of that enhances your system's performance.

Someone over on audiogon forum said the Maestro outlet was better than the Oyaide R1 and other outlets too..... http://forum.audiogon.com/cgi-bin/fr.pl Just click on the ( cables forum ) there.

I figured that out, Albert Porter is/was a huge poster over at the Gon. I've also read it on AA. I'm considering it for my room as I'll be short 1 a/c outlet and the Maestro may just be the ticket. It still comes down to what a person prefers in his system.

Sure...but spending more doesn't mean there will be, either. Just because you believe it is so doesn't make it reality. :thmbsp:
 
What is shocking is what audio asylum forum member Dr. Phil said....that the maestro outlet lowered the noise floor more than his $160 Oyaide outlet and with a $240 Oyaide wall plate too!...for only $79 bucks.

This happens when something seems counter-intuitive, strange, or (god forbid) can't be measured. It's funny how people dismiss this out of hand despite the large number of people who report positive results.
