Some Scientific Data on Isolation, Power, and Cables
Feb 9, 2010 at 5:20 PM Post #46 of 97
I went to the "Test Cases" page of the Acuity website, and nowhere does it indicate that this is a preview of more to come. It appears that this is it, in which case it's completely meaningless.

I remember hearing a while ago about Nordost trying to devise some sort of standard test to show that there are audible differences between cables. If this represents their best effort (and I hope that it doesn't) then they may as well just admit that their products are nothing more than jewelery.

The Nordost-Vertex-Acuity team said it was only a preview at the Rocky Mountain Audio Fest. They told the audience that more details would be forthcoming but they were still conducting the tests. They were excited about the results so they decided to do a preview according to Roy Gregory.

It was the Amazing Randi. He controls the purse however so his isn't exactly a fair test. Get a third party escrow on that million and get back to me.

Team?

I thought Acuity was supposed to be independent?

That's what it says on their website.

Acuity Products is a newly formed company providing innovative systems for the independent measurement and assessment of high performance acoustic and low noise electronic systems.

If you're out doing dog and pony shows for your clients, you're not independent. You're just a shill.

What a thoroughly awful and depressing thread this has been.

Curious, isn't it?

This reminds me so much of the "testing" Virtual Dynamics promised some time back. They made a Big Noise about proving their products with a research team at a university. Some months after they promised to deliver, a bunch of sketchy and inconclusive results were released, much like these. They promised more results, but they disappeared before showing us why charging $300 for Romex in a garden hose made things sound better.

TwoTrack, a truly open mind would also consider the possibility that you've been had by a snakeoil salesman.

Acuity has recently published some results that I thought many here would find interesting:

I thought Acuity were defense contractors?

Only Nordost's executive team (Roy Gregory, Lars and their CEO who I don't know) and Steve Elford from Vertex were there. They just presented Acuity's results.

I think you are really making a lot of stretch attempts to slander Acuity simply because they are working with people in the business. This is neither evidence for nor against any bias on their part. It would be the same if they were 100% independent which I believe they are based on the methodology described at RMAF.

If it's a fraud then its a very, very elaborate one.

It's a possibility but I think a very, very slim one. Why don't we wait and see how well their methodology and results measure up.

Yes, they went independent. I'm told they still work on SNR defense projects. Admittedly their website skills are lacking. May be DIY to save money as a new company.

Wow, TwoTrack I'm just as 'open minded' as you are but after seeing their site...

They're making it very hard to swallow any of it, wouldn't you agree?

So since they can't make a good website, decades of experience in signal to noise research and engineering must be poor?

I don't see the link.

There isn't much to read about the company on its website which makes it rather shady.

The link is if they were serious about their work and were truly professional, then they'd take the time to make a professional website.
