The Golden Ratio is [1 + (5^[0.5])]/2, about 1.618 (but an irrational number). It is better and better approximated by the [edit] quotients of the successive terms of the Fibonacci series, where each successive term is the sum of the two preceding ones. By the way, it doesn't matter where you start after a while, although 1 is the typical starting number and another 1 the next (hence 1, 1, 2, 3, 5, 8, 13, 21...). The series of successive quotients has an unusual distinction in being very slow to converge.

And let's send our donations to Noel, as Monster Cable has just parted ways with Beats by Dr. Dre, and he will have to scrimp and save to get his next Lambo. A marketing guy there quipped that at Monster the headphones are now known as Dead Beats.

(Actually the golden ratio is : 1.618)

That's odd, because I read about you guys discussing odd and even order harmonics, every day.

Heck even the "LOG" volume pot is golden ratio, to account for the exponential air pressure resistance at different SPLs.

The power levels needed are also exponential. Weather or not these correspond with some generally accepted rule of thumb is incidental.

lol

Correct, pick two numbers in the sequence, say 5,8.
5 x 1.61 = 8.05 8.05 x 1.6 = 13.02 13.02 x 1.61 = 21.06 and so on.

I think you are mixing Noel with George Cardas.
However, you also really don't know much about the cable business, as well. Nobody thinks that Noel is serious, anymore, about cables. But at MARKETING, he is a genius!

Pretty similar thing with me, as well. I am still using van den Hul's Hybrid 352 speaker cable (2x256 strands, silver plated copper with carbon fibre, hence Hybrid), which many people claim does nothing for them. Yet, it sounds just right for me.

Since due to room architecture I need faily long runs (2x6 meters, app. 2x20 ft), I suppose it's much more a matter of current capability of just about all the amps I have at hand and press into service.

At this time, cables are off my radar completely. I'm happy with those I already have.

I think tvr was just using Noel as a convenient and well-known historical example of a cable guy. Cardas has done a pretty decent marketing job on the Golden Section.

Yes, in the annals of marketing the man Lee stands (or in his case sits) alone. My understanding is that, as well, Monster Cable gets a signficant portion of their revenues from payments from people who were foolish enough not to realize that the company has copyrights on the use of Monster in most any way, shape, or form. I used to chuckle when I found that after purchasing the rights to call an SF ballpark Monster Park, most people thought it was after the job search site monster.com. But the latter is probably filling the Monster Cable coffers, along with the payments from hamburger stands and heaven knows what else.

How did it measure .....

Monster must still be serious, they showed me their 12K speakers cable set a few months back .



Poor Elliot .....

There is actually an oxymoron in your sentence.
A good mathematician is good physicist and a good engineer. Sadly it doesn't go the other way around. If you can't see it you're probably an engineer.

Andrew Jones is a physicist who currently works as an engineer.
You can find an interesting interview of Mr. Jones here (part 2 is here).

Concerning your other topic: Golden Ratio

Whenever one start to deal with scientific matters numbers such as pi , e , 1 , -1 or sqrt(-1) deserve more the "magic" quality attribute but i suppose that they are not as easily marketable than a number that is said to be gold made , litteraly when it comes to Audiophili$m...

But the most magic number is zero, certainly for audio. Zero distortion, zero dB variation in FR, zero difference between original and reproduction. We are asymptotically approaching all these zero's, but the logarithmic nature of the auditory system leaves us with endless opportunity to invent further improvements.
