NOS Western Electric wire used for power cables??

I've know a number of people who have implemented this grounding scheme with great results and at a significantly less cost than Tripoint charges for their technology.

Finally had some time to read post 28 in that thread.

I'm afraid Danmyers has some common misconceptions about "ground."

Namely the misconception that "earth ground," i.e. a rod stuck in the ground, has some particular relevance to an audio system.

It doesn't.

Many people believe that earth ground is some magical one-way drain for noise and RF.

It isn't.

He recommends using a number of copper braid ground straps tied to your components and then brought to a single point that's plugged into the safety ground socket on your wall outlets.

This won't help in any way with regard to EMI and RFI.

Now, what it CAN do is help reduce noise from the single most common source of noise in audio systems, and that's interchassis leakage currents in the safety ground lead of the power cables.

Long story short it's due to capacitive coupling between the AC cord's hot lead and the safety ground lead.

The safety ground is connected directly to the equipment chassis and in many components, the signal reference ground is also tied to the chassis.

Leakage current flows through the safety ground leads and because those leads have a non-zero resistance, there will be a voltage drop across them. This voltage can then appear at the inputs of interconnected components.

By using the copper braid to connect the equipment chassis to the safety ground socket (and it's only about that connection, not any connection to earth ground), you're creating a lower resistance path for interchassis leakage currents and subsequently a lower voltage drop.

However while it can be effective, it's really nothing but a band-aid.

The real culprit is the safety ground.

And it's only required on equipment chassis that don't meet Class II (double insulated) standards.

The manufacturers of low- and mid-fi gear have been designing their chassis to meet Class II specs for decades, and is why you see none of it come with three prong cords.

However the so-called "high-end" manufacturers have yet to figure this out and three prong cords are ubiquitous, even on equipment which may well meet Class II specs. So instead they foist three prong plugs on everyone along with the problems they can bring about.

Sadly, if a high-end manufacturer did come out with a product that didn't have a three prong cord, many would perceive it as some sort of inferior product.

There's an old expression: those that can, do. Those that can't, criticize.

What the $%#! have YOU ever done?

I've been involved with high end audio for nearly 30 years. I designed and developed my first commercial product some 20 years ago (you can see a photograph of it here). It was the inspiration behind Corey Greenberg's Aunt Corey's Homemade Buffered Preamplifier DIY article published in Stereophile back in 1991.

If you've ever read the article, I'm Elvis.

I've been involved in the online audio community for over 25 years, from The Audiophile Network BBS and CompuServe's Consumer Electronics Forum in the 80s, to Audio Asylum and diyAudio today.

Currently my company manufactures interconnects and loudspeaker cables and I'm working on some electronics I hope to introduce this Fall that utilize passive signal amplification, something I've been developing off and on over the past five or six years.

I also do contract work for several other audio companies.

Happy now?

Simple Q try one of the 8 awg Mojo power cords.
Then state your opinion. Do read your replies? You Sound very arrogant.
You seem to relish in arguing for the sake if arguing.
You asked the defintion of "works" I bet most everyone knew what that meant.

Jrn

Simple Q try one of the 8 awg Mojo power cords.
Then state your opinion.

For what purpose exactly?

And it's Simply Q, not Simple Q.

Do read your replies? You Sound very arrogant.

Why? Because I have opinions you may not agree with?

You seem to relish in arguing for the sake if arguing.

Nah. If I were arguing for the sake of arguing then I'd have to try and come up with reasons for arguing. Too much work.

You asked the defintion of "works" I bet most everyone knew what that meant.

So tell me what it meant.

I have to chime in again.

Miguel is WORKING on patents for his products, they haven't gone through yet. Once they go through he will be displaying all of his technology for the world to see. Be fair.

I have heard Miguel's Spartan and Troy products in his personal system. They are quite good. I wouldn't purchase them myself, but I also have 3 Topaz isolation transformers. Two of which lower the noise floor by 136dB and the third by 146dB. I have heard MANY high-end conditioners and not one comes close to the neutrality or sheer effectiveness of the Topaz. I have brought them over to quite a few houses (Ben, RX8MAN, and Agear included) and not one time did I leave them disappointed in the performance. Quite the opposite.

Next... magnets.
Cables of all kinds, and anything that has any sort of current through it creates a magnetic field. What you may not be taking into account is that when magnets are added together their magnetic field DECREASES. By adding magnets to cabling and various other products you are effectively decreasing the magnetic field around the conductor. The pulsing of the magnetic field increases resistance in the conductor. By minimizing this magnetic field and lowering resistance you have less distortion.

Let's also cut the crap here, Simply. Grounding systems DO make a difference. WHY they make a difference isn't quite what we're talking about here. The fact that Miguel has sold quite a few Troy units (an owner of which now owns 3 Mojo audio power cords AND is looking for an isolation TX) should attest to the fact that it is worth $12k in enough systems for him to be able to sell it. It seems to me that you are taking every point that someone makes and telling them why they are wrong. Interestingly enough, every point that has been made on this thread is a topic that has made not only a difference, but the SAME difference in every single system I've heard it in.
