Townsend Isolda cable

[Max Townshend]

Thanks, so like in my sim of an average cable, 60db down. Which corresponds to a .05db freq response variation from 20 to 20k. Inaudible. Still dont get how you used a short to get a baseline voltage. (0db)

The "short" is relative, but there are real wires and switches in the tester and it is the voltage across those components that are shown.

your mind is made up and it is a waste of time

You ought to say that to the AES.

I thought for a minute that you were a bit open-minded, but If you don't care about flat strips, then your mind is made up and it is a waste of time.

What? I thought you were selling cables with clear audible improvements. I want to hear those improvements and measure them against ordinary speaker cables. I will attempt to duplicate your measurements.

I have no need or desire to test wire strips and not sure who on earth would care either. Or are you saying your advantage is over strips of wire no one uses???

From a very old paper. The characteristic impedance of some speaker cables at audio frequencies.

It really only matters between 5kHz and 20kHz, where all the fine details lie. You have chosen mid Zo cables. What about Silversmith? https://silversmithaudio.com/ Zo 1000 ohms? Or Isolda Zo 18 ohms?

Well that would be the reference voltage everyone is asking for.

Why does characteristic impedance matter for audio frequencies?

The fine details are right there! 5k, 10k 20k.
Sadly the author is no longer with us.
The first thing that you should have done was measure the cables, Duh.

Yes, the differences are minuscule, but real. You can ignore them if you want low-fi, but not if you want hi-fi.

So with a 7 meter cable and 0.1dB less '20kHz' you consider this 'low-fi' ?
A difference of -0.1dB @ 20kHz between thicker lampcord and really expensive wire is really the difference between low-fi and hi-fi ?
That would mean a DAC that is -0.2dB at 20kHz and another at -0.1dB at 20kHz is the difference between low-fi and hi-fi ?

Yes, geometry does make an inaudible difference. regardless what the cause of it is. No-one considers 0.1dB drop at 20kHz 'low-fi'

Yes, geometry does make a nearly inaudible difference. regardless of what the cause of it is. Noone considers 0.1dB drop at 20kHz 'low-fi'

Yes, -0.1db loss at 20kHz is inaudible, but here is more going on than that and the is why there is a speaker sound debate in the first place and that is what this is all about.

 

[solderdude]

What else is (electrically) going on that IS audible and not caused by the 0.1dB drop ?

Apparently alpha brain waves?

I edited my question for clarity.

Brain waves are electrical.

Brain waves are electrical.

Van den Hul designed a brainwaiver hifi thingy, all very scientific:

Well done Alt.

 

[solderdude]

Brain waves are electrical.

And the price, looks and story of the cable will most certainly alter brainwaves when listening to music.

Gives a new meaning to the word "brainwashed!"

Well done Alt.

You mean Aalt... Aalt Jouk.
