Well, you have an advantage over me. I failed tenth grade English and haven't had a course since then. I'll defer to your skills in that area.

What's your evidence for this, please?

Yes, I can see that you're still confused. My sympathies.

there is NO claim. Not even in the opinion piece. The only thing that remotely comes close to a performance claim is that the interconnect does nothing.

The disclosure is as full as it could be - the quote on Steve's site is not unatributed, a link is given back to the full article. The only other thing I may want to know is whether the article was paid for in any way and whether the interconnects were bought or supplied.

You just said that there was a claim in your last post

From jkeny's website:

How do these modifications improve the sound?
By providing a clean, noise free supply to the clock & clock handling circuits we eliminate clock jitter caused by the power supply. This is a common cause of distortion in digital equipment. By doing this we can realise the full low jitter performance of the clocks & the sound improves greatly as a result.

Really, very interesting.

We have a cable on a web site that makes no outrageous claims what so ever, and people are digging for mud ???? Completely unbelievable! Pretty silly too.

People, the point is that when an advertisement makes a claim that implies a "secret" or wonder material so that it affects the current moving through a cable, that's when you begin looking for proof. That is the point where the advertiser should be expected to back up their claims. Clear evidence is normally expected, measurements being the preferred backup. Why measurements? Simple, they can be performed and duplicated by any other person competent enough who has access to the proper equipment.

Listening tests are also acceptable, but they are subject to more scrutiny. For an example, the NRC here in Canada has performed listening tests on loudspeakers and even arrived at a correlation between some measured parameters, and subjective responses from the listening panels. So, if the only proof and research that will be offered would be listening tests, it might be a really good idea to perform those tests in a scientifically acceptable manner. Looking at how these tests were run at the NRC would seem to be prudent.

I can't imagine anyone attempting to develop any product that makes a claim to be better in performance from all the other widgets out there to do so, without any basic research to convince them they are on the right track. Sure as heck a bank wouldn't float a business loan without something concrete to go on. They aren't that stupid.

Hi John (Keny),
Got caught throwing stones?
A person with an interest such as yours should think twice before criticizing anyone else's efforts.

After reading your web site a little, I was struck by the fact that your claims are things that can be measured. I see no valid measured information at all, and the 'scope shot you have showing the "ringing" may be caused by an improper 'scope set up. Attaching a diagram of how your equipment was set up for this test would really help assess how effective the attenuators are (or aren't). As for cable reflections, yes. I am aware of how that works.

I've also noticed that you are engaging in some personal attacks. That isn't allowed here, and that is why a recent post is no longer with us. You may address an idea or topic, but attacking a person is off limits. Not to mention that that activity is completely O.T. in this thread.

-Chris
