Re: Audiophoolery?
An Arcam amplifier of the late 80's had two rings of copper about an inch across on the PCB to "make it sound better" this was suggested by Peter Belt... https://www.stereophile.com/content/...belt-1930-2017 Arcam hired him at some cost for this, 'spose it was good for advertising.

I'm suddenly wondering if that will be shown to be the cause of the B737 crashes, not using grain-oriented, oxygen-free, cryogenically treated, lead-overwound cables and connectors for the digital fly-by-wire signals? |

In other words a sensor, a cable and an amplifier. Anyway, although those truly skilled in the art can certainly design a suitably wideband input filter, I'll bet a quid that the vast majority of commercial domestic audio amplifiers are not at all well filtered.

Re: Audiophoolery?
Totally OT for this thread (love that it is now a sticky, what fun). Always fibre optic for digital audio, cheap and no chance of a hum loop. And I like the red light.

Coax actually can work much better if done right. By that I mean galvanically isolated at send and receive, with true resistive 75 ohms at each end (and there is a much longer story about that relating to pulse transformers actually not being best at 75 ohms), and a halfway decent 75 ohm cable. |

Re: Audiophoolery?
That is ridiculous in the extreme. Like beeswax filled fuses https://highend-electronics.com/prod...wax-super-fuse ($175 per fuse or $225 for the super version), Bybee Quantum Purifiers https://bybeetech.com/products/#puri...%93diy-and-oem
And in fact any audio product that includes the word Quantum. And there are quite a few. Quantum fuses https://highend-electronics.com/prod...-quantum-fuses Or the Quantum Line Strip, which features Quantum Tunneling Treatment (what tosh) https://highend-electronics.com/prod...tum-line-strip The audio world is full of this sort of nonsense, all with a massive price tag. |

And the sound is indistinguishable from a wind-up gramophone (sorry, could not resist). I don't think I'd want wax-filled fuses. Sound like a major fire risk if they blow. I want my fuse wire surrounded by something that won't burn, like sand. |

Re: Audiophoolery?
A fuse is just an ordinary piece of tinned copper wire. Why should it benefit from beeswax and not every other conductor?
Making and selling non-BS1363-compliant plug fuses could be taking on a lot of liability. The thing is it's so easy to fake these advances. The first of April is close, so how about a suggestion that amplifiers, speakers, turntables etc made in imperial dimensions sound better than those made in metric dimensions? It would have to be padded out with florid prose and tales of exalted listening tests then an attempt to flog imperial-sized CDs at exorbitant prices with the promise that an imperial CD player would follow. It was no coincidence that we played 12" records on 12" platters with 9" arms and cartridges on 1/2" hole centres through 12", 4" and 1" speakers. David

Re: Audiophoolery?
I recall hearing about a HiFi enthusiast who went to such lengths to reduce the effects of the cable to his speakers that he had channels dug out out his concrete floor and filled them with mercury.
Now there' a new marketing idea, it has the advantages of being both expensive and toxic. Peter |

Also, if you are going to measure your tracking force in grams (probably centiNewtons in Germany .....), it would be bad ju-ju to go mixing your units. Some early Eastern European ICs were made on a 2.5mm. pin pitch, not realising that the extra 0.04mm. was no error. Would their rarity compensate for the rough-and-ready, make-do-and-mend attitude stereotypically associated with Eastern Europeans, though?

Re: Audiophoolery?
Not sure if this has been seen before but I thought 'wooden capacitors' made for amusing reading https://www.dhtrob.com/projecten/elna1_en.php
Improve the sound of your hi fi by giving electrolytics a wooden case......

Re: Audiophoolery?
Good thinking! Just imagine how a system might sound if the 'speaker cables were routed through copper tubing filled with... well, ideally beeswax, but even liquid paraffin would surely be transformative. Give it a month to settle before use, then listen to the difference it's made, and you'll be itching to seal the base of your amplifier and fill it up with wax through those handy perforations at the top or my name's not Jack Robinson. It'll need an hour or two to burn in of course.
