Kimber RCA Cable vs Amazon Basics (Video)

[Geert]

I suspect mr PhilDel ( whoever he really is ) is not participating in good faith he seems to sling walls of AI text at us and don’t substantiate any of the claims .

He dropped off after AI let him down when searching for support for the idea of dielectrics memory effect in audio cables. This is Claude's IA stance (since ASR members can't be trusted on this topic ):

Is There Scientific Support for It Being Audible?
This is where the science becomes much murkier, and the honest answer is no — there is no credible scientific evidence that dielectric memory in cables produces audible differences in typical audio applications. Here's why:

• The magnitudes are vanishingly small. The capacitance of a typical audio interconnect cable is in the range of 50–200 pF/meter. The charge stored, and the residual "memory" voltage, are orders of magnitude below the noise floor of any audio system or the threshold of human hearing.
• Audio frequencies are relatively slow. Dielectric relaxation effects are most significant at very high frequencies or in precision DC/low-frequency measurement circuits. Audio signals (20 Hz–20 kHz) are slow enough that most dielectric effects are negligible.
• Source impedances matter. For dielectric absorption to have any meaningful effect, you'd need very high source impedances over long timescales — the opposite of typical audio circuit conditions, which involve low source impedances and AC signals.
• No controlled listening tests confirm it. Blind/double-blind ABX testing — the scientific standard for audibility claims — has never reliably demonstrated that cable dielectric material produces audible differences in audio systems, controlling for other variables (resistance, capacitance, inductance).

Let’s stick to more technical discussion here and avoid personal commentary about others. Thanks!

If they follow the AudioQuest route, expect a cease and desist to come with the threat of legal action.

Have to say that this looks like actual writing as opposed to AI scoop (data, writing templates) and serve.

Ms Papadopoulos does a good job summing up the situation. Easier to believe in a $4,000 wire than rearrange the furniture.

I noticed that yesterday. Seems to be a syndicate article making rounds.

Has anyone seen this? These guys are claiming they can measure cable differences that AP analyzers miss — something about geomagnetic field
compensation and latitude-dependent grain orientation in copper. They replicated the "$7 vs $4k" test at 0.0000° latitude and got a 2.3 dB spread.

The section on SINAD not capturing harmonic structure is actually interesting. Same argument as why tubes measure worse but sound different.

Yes but the harmonic structure only matters if something is clearly audible , if you suppress distorsion far past any audible levels it can have whatever disharmonic structure it wants to , it is true that more horrible sounding distortion is more audible because it does not mask that well with music, but we are in practice way past any levels of detectable distorsion so this does not matter.
You can also talk about the quality of noise in the same way some electronic noise is more pleasant than other noise , but it also only matters if you can hear it .

Some speculate that some prefer some tube equipment due to its audible distorsion , but they refuse to call it distorsion

This is contested because there or not much of real controlled tests and much tube stuff is bought with the eyes and marketing story . So some tube equipment is not "bad enough" to bee an sfx effect generator for all music all the time .

Is this a new Geoff Kait endeavor?

I think their entire website is satire.

Or at least I hope it is.

Somebody, please, tell me that it is.

 

[Beave]

Now that I've looked at it a little more, that site is pretty impressive (in terms of being outrageous satire).

Somebody has put a lot of work into it. I wonder who is behind it?

Superconducting cable on their site, 42000$/meter/pair. Yes it is an obvious satire, Ai generated.
Funny.
Edit: I looked into it further, it's sometimes hilarious, and very well designed, kudos.

But sometimes they run secret sales where the purchase price is lowered to a more reasonable $41,999.96. Just be patient.

Considering that the earth is spinning at 1000 miles per hour, the dB variation would naturally be all over the place. For this reason, I made instantaneous measurements lasting just 1 nanoseconds. That way, the earth's spin was completely excluded in my measurements. They likely did it much slower causing that error in their measurements. I teach how to perform such measurements correctly in my online class (cost: $4,250).

Are you suggesting that The Journal of Equatorial Audio Science is a foolish endeavor?

I mean, the Geddes & Lee research on correlated harmonic distortion thresholds is real. That part checks out. Whether latitude has anything to do with it is... another conversation.

At what latitude shall we have that conversation?
