I see they still call it the rarest hardwood, far from the truth. At least for Oregon myrtle I found ~$7 BF wholesale. An easy DIY 4" thick slabs could allow cutting all you need from one piece, think of the seamless integrity of the sound.

Go back and look at the patent that I have the link for

I've looked at the patent, which claims the invention of a ferroelectric field coupling device.

. . . as reported by audiophiles that are skilled in the art, in the context of a high-end audio systems, ferroelectric materials, when used for power line noise reduction, tend to have superior sonic characteristics.

Hello? Would one of those audiophiles stand up and be counted please?


In the interests of the 'art' of audio, please re-submit your report to this thread!

Many people have found thru listening, that Ferromagnetic material like ferrite clamps and rings sound bad. They affect the sound in a bad way. I believe it says this in the patent. Forum member Charles Hansen (RIP) talked about how ferrite should be kept away from audio equipment.

Whether ferrites do harm to audio depends on which ferrites and how they are used. A blanket ban of ferrites would be as silly as a blanket ban on ceramic capacitors.

But Ferroelectric material does not have this problem, that is one of the reasons Shunyata uses it.

Are you saying that any ferroelectric cannot have this problem, or that specific ferroelectrics do not have this problem?

What about the problem that the ferrolectric filter described in the patent doesn't do anything useful below VHF frequencies. How do you remove lower frequencies from your mains supply without using ferrites?

I still think "pedantry" is useful if you discuss the correctness of information; hadn´t you objected to my post about "complex wave impedance" i hadn´t noticed that a problem with my usage of the terms exist.

Sorry, the temptation to correct a pedant was irresistible. My apologies.

I am sorry but I’ve never seen such a noisy cardiograph trace with ordinary hospital installations like the one shown as “without Hydra Power Conditioner”, not even with elementary cardiographs plugged into standard wall outlets in a physician’s office.

Oh for goodness sake, they have a ground loop.

The equipment is sensitive to grounding of the patient.

One of the patient electrodes is a ground reference, the patient is touching metal that is earthed.

So how would one go about measuring line power noise with a sound card?

Say one was shooting for 96KHz or 192KHz bandwidth.

Transformer coupling is probably right out unless one had a transformer specifically wound for the purpose. Typical power transformers like a 120VAC:2.5VAC filament transformer wouldn't have the bandwidth.

A resistor divider is simply asking for trouble from a safety standpoint.

What about capacitive coupling with film caps, then high pass filtering before the sound card input to reduce the 60Hz component?

On the Electrocardiograph shill video the thing I never got about that is that wiring codes for that sort of an installation are, at least in UK very tight. So unless they found a real life Dr

Nick, how did they get that stuff signed off?

Argh! I read chopstickaudio....

... Maybe I'll have to look into doing some DIY chopsticks, to improve the perceived experience when eating sushi and listening to music at the same time? Would it be better to do a matte absorbing surface to reduce possible reflections? Could possibly help improve grip also. And the missus a.k.a. "boss lady" would probably be happy I made something not so obtrusive for once...


This actually turned into quite the useful thread after the mindless bashing ended.
My sincere thanks to everyone involved.
