Everything you said is true. A proper EMI filter like Maty shows above, and/or ferrite beads on the cables is usually the cure. Snake-oil cables for ridiculous prices, not so much.RFI filtering of input AC lines can be useful if you are in an environment with a lot of RF energy in the air - like near a TV or radio transmitter of significant output power. For example, I used to live in a high-rise apartment near the Sears tower in Chicago which had, at the time, something like 550,000 watts ERP coming off the antennas. My apartment was not all that far from those antennas, I was near them both horizontally and vertically. This was in the days before the digital TV transition; I could hear the sync buzz on my audio system no matter what I did. I could watch certain stations on my TV and hear the difference in the buzz between dark scenes and light scenes. I had all NAD gear at the time, including their top-of-the-line Monitor Series stuff. These units had the same "your equipment has better filters in the power supply than any external accessory..." circuits in their power supplies, yet I still had RFI. There's common-mode RF currents that get into your gear, especially at VHF and UHF frequencies and solid state parts can act as detectors for this stuff and change the RFI into buzzing sounds etc. Even though the power supply filters out the transverse-mode stuff, for the most part the common mode stuff still gets in. So there IS a place for things to reduce RFI in audio gear in certain situations. I never tried anything to address the RFI situation; I just put up with it. I didn't live there very long. After I moved, the sync buzz from Channel 32 (I suspect it was Channel 32) vanished.
Jesus Christ. This is robbery in daylight.Last night I was looking up Joe Skubinski online to see what his background is. I was not involved in this discussion below, nor can I confirm it is correct. But this showed up in my searches:

I somwhat agree. But on the other hand it is important work to uncover these shady things, even if I can imagine amirs patience must be tested good while doing these measurements..While I understand the reason and importance of testing also useless audiophoolia I would also vote for
1. Waste of ASR resources and Amir's time (piggy bank panther)
and instead of such or another 100+ SINAD China DAC review would rather see measurements of decent loudspeakers or headphones where audibility really matters, especially since Erin cannot review them since some last months.
I apologise for the whining but it's the way I feel.
My advice, don't feed the troll.But why would I even want to?
they are like leeches live off audio industry, but they are not alone. the amount of snake oils you can spend money on is staggering.LOL I remember this, what an ordeal that was.
This whole ordeal of wrapping cables and hiding sources is just hilarious to me. In the same way it's hilarious that original architects and manufacturers of these cable parts deal with sales in the millions of units, and is weird to see none of them (the people with the actual capability creating the entire cable and it's parts) don't sell their own "high end" ultra expensive variants for the consumer market.
It's so idiotic on face value that I just cannot understand how this secondary cable industry still lives. If they actually manufacturerd all parts of these cables and such, I'd somewhat be able to stomach it. Otherwise it just feels like fraud off the jump. There are thankfully cable sellers who are transparent about their sources, and what they're doing. It's also interesting how none of them are pricing their products this insanely high.
Uhm...in what way are these cables great? Cute dog.I think the polling is unfair, as with the other two cable reviews this week. These cables are clearly Great. They are also a Waste of money. These are orthogonal.
And I don't understand all the hatred for something that costs 10x as much as a competent alternative. We here at ASR seem to manage tolerate people who want to spend the cost of a luxury car on their loudspeakers when something that costs 10% would do an excellent job.
And in case you think I'm one of those that gets a kick out of having fancy cables, here's my "high-end" home entertainment system.View attachment 270441
Hi Maty, long time since I’ve seen you. What application were you using this for and what problems were you solving? Did you do any pre/post measurements of the output of the device?It is better to build a small cable with an RF/EMI filter to which to splice the power cable or the powerstrip.
An old picture, with my first try (teflon+duct tape).

The diyAudio First Watt M2x
I removed the Tucson boards and put a jumper across 2 and 4. Using my phone as a signal source the M2X now plays much louder than when the boards were in place. Finally sweet, sweet music! While I think about what could be wrong with my Tucson boards, which by the way are using OPA1611 op-amps...www.diyaudio.com
[ RF/EMI Schaffner has the greater attenuation graphs. Years ago I researched deeply and that was my conclusion. Schurter, for the IEC connectors without filters is my other choice.
As Mark says, you have to choose the one with the tightest amperage because the attenuation is greater. I have a lot of 1A and 3A. And one of 6A and other of 8A (power strip). Spain: 230 Vac, 50 Hz. With 115 Vac you need double amperage.

You can conceivably get more by paying more for speakers. What is your reasoning for paying more for cables to get nothing? That simply seems foolish.And I don't understand all the hatred for something that costs 10x as much as a competent alternative.

Don't @amirm 's measurements show practically perfect transparency? They perform! Idk for sure but they look solidly built. Maybe they last for years. What more do you want?Uhm...in what way are these cables great?
Conceivably, yes. But let's take a browse through the Most beautiful speakers in the world ? thread. We see a lot of lust for fancy-looking expensive things that conceivably deliver higher performance than <whatever benchmark we choose for speakers under $5k each> but probably don't. In fact, with a lot of these weird constructions, there's good reason to suspect that they perform worse. But do we feel the need to rag on those that lust after them? I don't. I think to myself, "Really?! You want these Doctor Who monsters in your living room? Oooookay." Alright, now I said it out loud, or typed it into the computer more like, but I'm trying to be nice about it in a friendly teasing way.You can conceivably get more by paying more for speakers.

They are also a waste of money, of course. And? So are a lot of things.

You got me thinking. Conceivably is the space where all kinds of interesting possibility exists. Quantum uncertainty theories of free will. Esoteric initiation and invocation. Cold fusion. Reincarnation. Ecstatic ritual. AI. Conceivably is the space where we can play with magic. High end speakers that delivering better music and, for some, patch and power cables that sound better. My question is about why we single out cable lovers for special derision.Your dog is cute. I don't at all understand your points of view. But feel free to pay too much for everything![]()
