Just more of the same audio has to offer: BS, voodoo, myths, unsuported claims, expensive price tags for what is offered, etc.
And, in this case, it is ugly.

I can understand making an expensive power cord at least look like it is worth the mony, but these power cords look like something you would find in a McDonalds happ meal for audophiles.

"...and would you like some hype with that, sir?"

LOL! Of all the marketing rap I've heard about anything associated with audio, Mapleshade takes the cake.

I hear they make very good CD recordings. They should stick to what they know best, recording

Hi mtry

they actually do make some pretty good Cd's. I'm not sure what type of music you enjoy listening to (why is that?)...but their sampler (music festival) is worth looking into. Good music and good recordings. I enjoy them.




oh...yeah. The MapleShade tweaks? no thank you.

What is that clearly visible green straight thread/wire? The ground? Sooo thin.

Probably. Hopefully it is of sufficient guage to trip a circuit breaker(or fuse) in the event of a short.

BTW - it gets even better, this was in the (online) Owners Manual:

"Never lay this (or any other wire in your system) on a carpeted or plastic tile floor—nor any plastic molding or plastic wall covering. The proximity of bad-sounding dielectric will seriously degrade the sound of even the best cables."

hahahaahhahahhahahhahahahhhahhahahhaa

Man.....these guys are really twisted.

Mapleshade makes some great sounding cables. With their return policy it's a no risk deal.

Is there really any great risk? lol


He has philosophy about cables, which is 'thin'. He helped develop the Omega Mikro cables which have been very well received. The guys is a world class engineer. You can't disqualify him on that basis. He was instrumental in the development of the F-16 from stem to stern. He knows his ****. I think his stuff has a very good sound and the science behind his ideas really can't be challenged. He does what he does for a reason. I'm not going to say I think his products sound the best that is out there, but they aren't that far behind.

The reason that powercord looks the way it does is because of his beliefs about the dialectric. He thinks 'air' is the best.

He has what? Philosopy? What he needs is evidence for his philosophy. After all, it isn't a mystic.
And his idea certainly can be challenged. He has zero evidence for any of his cable ideas making audible differences, zero. Certainly not supported by DBt listening.Certainly he has not produced that evidence.

Just because he is a world class engineer doesn't mean he is on the same playing field in audio cables. Far from it.

He does what he does because there are gullible audiophiles, maybe himself included, that buy into that nonsense.

His evidence is the the people that buy his products and enjoy them. That is all the evidence he needs.

Gullible audiophiles? Far too many folks have enjoyed his products for it to be considered nonsense.

As for the dbt nonsense. That is your standard, which you have every right to have, but it by no means invalidates his products. Listen to any of their recordings and they are leading edge as far as sonic reproduction. He employs his 'nonsense' as you put it it into every recordeing and they sound magnificant.

Hold on there young'un ... your gullibility is belying the moniker you've chosen for yourself here. This entire Mapleshade "business" (the accessories biz - not the recording biz) is a sham - a hoax - a disgusting ploy to extract cash from the unwary, gullible audio CONEs on totally false pretenses. The leader of this band of thieves may be a talented recording engineer, but he should stick to that career. If that enterprise is not financially successful enough to suit him, he should just throw in the towel and go to work for someone else. This decision to expand his business into dubious cable designs and power cords, strips, etc. is a shameful way to conduct a business ... shame on him.

In order to make you a bit more of a "wiseburro" about audio than you presently are (since you're willing to believe all of the ridiculous claims made), I must tell you that a power cord - no matter how it's designed cannot have any meaningful effect whatsoever on the performance of an electronic product to which it's attached ... period! And dat's da troot.

That is an incorrect one..

If all the equipment is designed to meet specifications by eliminating the equipment's dependence on an external reference ground, then your statement is correct.

Pro equip is well equipped to do so, with balanced inputs..Home audio is usually not..

How many people out there hear a thump in their powered subwoofer when something electrical turns on or off? It's not coming in via the power cord, but is coming in via the ground loop..

Most, if not all, of the powercords made do not worry about that...just current delivery to the equipment..

Welcome back. Haven't seen your postings in a long time.

While you are technically correct about grounding, the implication of manufacturers of power cords is that somehow, the ability of the power cord to deliver current from a wall outlet to the power transformer of electronic equipment in some way alters the performance of that equipment. This on the face of it seems ludicrous. As you know, the power cord is the least significant element in the circuit which comprises the utility transformer secondary, feeder cables to the service entrance, the branch circuit conductors, and the transformer primary of the electronic appliance. Grounding MUST conform to NEC article 250 and to the conditions under which UL approved the appliance for its seal. The inability of electronic equipment to meet its performance specifications for noise and distortion due to ground loops is usually due to limitations inherent in the design of the equipment itself which includes its manufacturer supplied power cord and local conditions of the power distribution network. It is true that multiple service entrances and complex cable, and telephone interconnections can create additional ground loop problems which usually have to be dealt with by installing a single signal reference ground. This is typical for office buildings but can happen even in homes and I've had the experience of it in my own house connecting TVs and VCRs to different cable outlets and then to each other forming a loop. Manufacturers of these cables further try to alarm consumers into buying their products by implying that rf noise somehow parasitic to power distribution will compromise performance of their equipment. It is clear from the Mapleshade power cord pictured on the referenced web site that this was not a concern here as there is not even the slightest attempt at shielding. However, parasitic capacitance suggested by the twisting of the conductors and inductance suggested by their spacing could act as an rf filter but it is hardly worth $150 but more like $1.50.

Most advertisers of audiophile power cords have some gimmick to lure customers. One says his cords are made from a single crystal of copper with no grain boundaries. Some have odd geometries. One even has a dangerously removable ground pin on the plug. Once ungrounded, the appliance no longer conforms to UL if the original equipment was supplied with one and a short to the metal case could cause exposed live parts creating a hazard of electrocution.

In an 11 year stretch of building laboratories for the research arm of the Regional Bell Operating Companies (RBOCs) including installation of some of the most sensitive measuring equipment available, I encountered may grounding schemes including some crazy ones that were requested. But in all that time, I never saw a piece of bench equipment that was supplied with anything more than a standard power cord and although there were occaional requests for UPSs to protect experiments against power failures, no special precautions to get the most performance from equipment of that type was ever requested prior to or subsequent to installation. That strongly suggests to me that the need for it in a consumer audio amplifier is completely bogus.

I find I am "required" to copy and post a lot of your talk about this...although I agree with all you said, I prefer it remain intact, a constant reminder to all that the issue is that important..thanks..

But in all that time, I never saw a piece of bench equipment that was supplied with anything more than a standard power cord and although there were occaional requests for UPSs to protect experiments against power failures, no special precautions to get the most performance from equipment of that type was ever requested prior to or subsequent to installation. That strongly suggests to me that the need for it in a consumer audio amplifier is completely bogus.

At work here, I find a lot of exception to that..a lot of the 12 phase supplies, especially the ones over a quarter megawatt, create all kinds of ground bounce issues. The 5 megawatt one a quarter mile away also raises hell..And, all in an environment where we're trying to measure tenth microvolt signals riding 30 Kiloamp super loads..

So much of the audio stuff we use has no regard for grounding issues...leaving the consumers to figure out hum and noise issues. It's no wonder the snake oil flourishes..

I think this is the key statement. You are relying on your experience in another area to make an assumption on consumer audio. Have you ever tried switching out a powercord?

You have not one shred of 'evidence' to back up that ludicrous assault on Sprey's character or his products. Shame on you.

You are touting your opinions about powercords, and nothing more.

Why do skeptics always have to rely in the histrionics of insult?

[skeptic]

Here are some numbers. These are typical worst case real world numbers.

Say an audio amplifier which is 40% efficient is putting out 200 watts per channel and all of the current is coming from the power transformer. It draws 1000 watts which is 8 amps at 120 volts. At that point, it has an effective input impedence of 15 ohms.

16 gage AWG has an impedence of 4 ohms for 1000 feet. A 5 foot power cord of 16 gage wire will have an impedence of .04 ohms. The voltage drop due to the power cord is one third of a volt. If an audio amplifier can't handle a one third of a volt drop, it isn't much of an amplifier to begin with.

Here's a web site for wire impedence by gage if you want to try the calculations yourself.

I just wanted to add that whenever you make claims about his motives or character without any evidence you become exactly what you accuse him of being, if not moreso.
