Possibly. Methinks there may have been some marginal stability issue.

This Golden Ratio was used to compose this song using nothing more then the Fibonacci ratio.
Who says musicians are talented, I say they are good with math.
Debussy: Reflections in the Water - Images, Book 1 - YouTube

Here is another fine example: Sonnneries de la Croix / Eric Satie

Yes, and Harmony of Universe is in the roots of ages old Rosicrucian teachings.

I'm not certain, as there are many Andrew Joneses, but he may be the speaker designer who used to work for Infinity and has more recently been with Pioneer.

I would add to the "hierarchy" at the head of the AJ list, the Platonist philosopher, who introduces the notion that numbers are real.

I have a great anecdote about the response of the mathematician, the physicist, and the engineer to the proposition that all odd numbers are prime, but this thread is hard to get through already

Yea, there are a few hints at that! I notice the compensation got simpler as he progressed through the the servo 100 series. I am still struggling to understand all of it. I hope Simetrix helps.
With Exicon outputs, still seems stable. Never noticed, Fairchild is nice enough to provide Spice models.

Now, here's a thought to tickle my curiosity. Good thinking, Brad, thank you!

And all this while, nobody, not even those known to use them, has even mentioned capacitance multipliers ...

Odd little circuits. They are most deceptively simple and easy, but getting one to work as advertised is no easy job.

Golden ration, is 3-5-7. That does not show up in Fibonacci.
Both sequences show up in nature. We seem to be attuned to them. Pleasing to look at, pleasing to hear. Fractals show up everywhere too. But still, I am waiting for someone to suggest how this has anything to do with amplifier circuit design. Don't bother if you suggest it has to do with "optimum cable stranding" with all due respect to Noel, he has made a tidy living at it.

I am, at this very moment, listening to an optimum stranded cable designed by George Cardas, first used by Enid Lumley, and it STILL sounds just fine to me. Beats zip cord, or cheap RS or Monster Cable. Go figure.
