This has not been proven. The claim is marketing not science.

"When I plug in my ludicrously expensive cables and listen with a totally unbiased ear, it definitely sounds better"
That’s the problem - only a few people can admit that the expensive thing doesn’t doesn’t deliver. Things should be measurable with the right test (to the ear) however inside peoples heads may or may not actually be measurable.

What cable risers would people recommend with my speakers :0)

Celestion A Series
I own a pair of Celestion A1, A3 & A4C. Why is it every single pair of these for sale have treble drivers pushed in? Either that or the cabinets look like they've been thrown down several flights of stairs. It took me years finding these speakers, most had either treble driver poked in, damage...

Its quite telling that when they talk about these products, they always mention the cost. More expensive is more better!
Sound waves are measurable. It would be very easy to analyse the actual difference all these things make. Curious that the industry relies on subjective airy-fairy 'feels' rather than quantifiable improvement.
I'm surprised we haven't been swamped with AI audio stuff yet, seems an obvious candidate. Sample loads of high-end hifi kit and try and manipulate the sound to get that from lesser equipment. The very thought I'm sure makes the purists retch
Well done!! You certainly fooled us. For a long time most of thought you were serious.
Now with this statement about fuses we know you have been trolling us all along. Well done for keeping it going for so long.
Because nobody would be gullible enough to believe a fuse could make a difference to sound Quality.
EQ cannot fix room issues, it can only mask them at the calibrated listening position. A DSP that uses spatial tracking to adjust based on the listeners position in the room could be interesting. Still won't be anywhere near as effective as fixing the room issues in the first place though!

Why would they lie? I've sent my life savings to a person who is orange he said that money will be used to investigate election fraud.
I can only imagine the laughter in their office whenever they sell one
No different to ripping off elderly senile/dementia people off tbh. I wouldn't do it, and refuse to put the sale through.

Exactly, treat the room and stop spending thousands on products which may or may not work.

Regarding that video with noise waveform.
1) Was in gigahertz and megahurtz range. Will have no effect
2) Did he show the output from the amplifiers own PSU -> storage, and storage ->rest of the component? Or just the mains level?

Imo it's hard to do a proper, accurate test at home. Unless a speaker is connected with cables/fittings a, then another with a different setup so it can be quickly flicked to that one. In reality, by the time you do these changes its probably 30 mind, and you've just spent a large amount of money on stuff, of course it's going to sound 'better' (can't remember the phrase but its the placebo effect with a fancy name), but obviously this is subjective and probably just sounds different (or maybe even not different at all). Reducing noise is good, but imo if your noise is already low (which I'd imagine most setups will be), you will only see it on a scope, but won't hear a difference."When I plug in my ludicrously expensive cables and listen with a totally unbiased ear, it definitely sounds better"

Not to mention most of the people who have the income to afford all the audiophile snake oil are older and their hearing would have lost sensitivity due to age so definitely won’t be hearing real differences.

Also find very snobby and up themselves, rather more relaxed and chilled out. Likely to spend £5000 on stylus etc, and put their nose up with people who use bass management, room correction, subwoofer, streamers, thinking wave is better than flac, and over wifi/ethernet is worse SQ than playing from a CD, or vinyl.
Noise in audio..
1/f noise - bad for bass, noise in the audio spectrum - bad, noise above audio spectrum - bad too. Noise can suck power in the audio range, can cause instability causing degradation of signal or even destruction of component, to changing of harmonic structure etc.
People will listen to higher THD for example if it sounds better to them for example..
This is a Wattgate 350 EVO RH, they make a better connection with the IEC connection.
This is over £140 retail for the wattgate separately. This is connected to a Powerkord 300.
This is the inside of an older RA reference cable plug. You can see the 8 live and 8 neutral copper cores, each core is high purity copper with kelvar dielectric. It's the twisting of these cores in a weave that reduces EMI / RF entering the component. When you reduce the noise you increase the detail. The black fuse a RA super fuse.
The component you see between the neutral and earth is part of a clamping device, and was NOT added by Russ Andrews and added after the cable was sold.
The entry level RA Yello powers are a significant upgrade over a £5 standard power cable. However a cable such as the RA Powerkord 300 is again a significant upgrade over a RA Yello power.
Hmm. So someone has put either a MOV or a cap between neutral and earth.. Also that shielding for the cable is basically looking like it's touching neural.. I would expect the shielding for the cable to be grounded..
I *really* hope that is a safety rated cap that fails open.
Now in my amp.. I have an IEC inlet filter - it consists of a safety cap across the pins, an inductor and a second safety cap. so noise in the cable gets targeted before it gets into the chassis. Add a shielded mains cable and.. well.. that's about £30.

There is no outer shielding on that cable, it's just a nylon braid. The shielding is done by the Kimber Kable weave.
Over the cap, those have been my thoughts also. I have that in one cable only, that cable is not in use at the moment.

As counter-intuitive as it might seem it isn't always beneficial to remove noise in the local environment to far from the electronics of the audio device, at least not in an ad hoc manner. Some amplifiers for instance can more effectively remove noise when it is present on all inputs.
