Speaker cable recommends please..

Just had a quick look at the Tellurium Q website. With regards to the 'Tellurium Q effect' - the reproduction of a square wave:

1. There's no way that any DAC on the market could reproduce their 'signal pulse' as it has perfectly square edges, which would require an infinite bandwidth.

2. The signal pulse appears to have a fundamental wavelength of 2 µs, giving it a fundamental frequency of 500 KHz (the lowest frequency it contains), which is about four and half octaves above what any human can hear.

3. If you believe they've actually done this experiment, take a look at the response of the cheapest cables. They look like they would have reacted to the first edge of the pulse in about 3 µs, meaning that they would be capable of reproducing frequencies up to 166 KHz - still nearly double the frequency that the highest quality digital master recordings contain (96 KHz) - and even most audio pro's consider using that sample rate a waste of time.

Lastly, you're probably getting bored by now, but minimal phase distortion isn't audible, or even important above 10 KHz, as most mic techniques and reverberant rooms totally 'randomise' the phase up there anyway.

When Abbey Road are happy to use £2.50/m speaker cable with £18,000 speakers, then so am I!

When will people learn that the laws of physics don't apply to HiFi? Also, the last thing anyone connected with HiFi wants is someone who knows what they are talking about.

You tread a dangerous road

Personally, I put it down to Easter, and the consumption of more than an ample sufficency of cocoa.....which can be a hullucinogen, giving similar effects to LSD.

And you've obviously had plenty of it then Cno...!

Welcome to the boards Tonmeister. Good to have a pro's perspective. No storms from me incidentally...

Yup, right up there with a good Tom Clancy...

An oxymoron if ever I saw one...

Apologies in advance for the slide off-topic, but he knows his stuff, but to the point his novels become a little too detailed - you could easily lop off 250 pages in a Clancy 1000 pager and still have a good read!

More professional pespective to balance that of hobbyists and sales personnel is certainly welcome.
