Snake oil?

Post by Phunky »

Hi,

Skip to 8:45 in the video linked below and you'll see some strange poles with ice hockey pucks attached. They are supposed to work wonders for the sound.

Here's what the manufacturer has to say about the product:

I assume that it's snake oil. Please don't tell me that I'm wrong :headbang:

Cheers

I'm STILL surprised at the proportion of pages hi-fi magazines (even the more respected ones like Hi-Fi News) devote to reviews of cables, eulogising about the sonic improvements they make, and insisting that at least 10% of a hi-fi system's budget should be spent on said cables :headbang:

But then if you count up the number of pages of paid advertising for said products in such magazines, perhaps I shouldn't be so surprised :smirk:

Cynical? Moi? :beamup:

Don't all proffesional recording studios use Mpingo discs??

It literally brings the music hall into ones listening room as though the walls have disappeared

Why do we spend money on real acoustic treatment - when a few circular blocks of wood will fix everything" ;)

Here's the 'technical report' on the discs. http://www.shunmook.com/explained/HK-TN ... %20-LH.pdf

Now I see where I've been going wrong with this Rockwool. Page 4 of the technical report refers to 'Divine Wood'. My Rockwool clearly lacks the required divinity.

There was me thinking that I should employ an Acoustic Consultant when what I really need is a Priest. :angel:

OK. I've just been doing some research into 'Divine Wood'. Now I need to delete my browser history :blush:

Scrolled through a couple of reviews and the general consensus among the audiophiles seems to be that the discs are "room resonators" :lol:

Yep, that's exactly what they claim in the technical PDF Wonks linked to.

The theory still seems bizarre, but they appear to be designed to add resonant energy to the room to even out any existing resonances and add liveliness to the room (the opposite of absorption).

I've got a radiator that does that if I'm not too careful! :headbang:

(but only of course at ONE frequency, so nowhere near as effective as the Mpingo discs :beamup:;) )

So they are really the opposite of room treatment, and increase reverberation times and harmonics. Lovely.

Exactly, and that leaves the engineering types among us feeling rather rattled ;)

I reckon it's a real bargain... a basic kit only costs around £1k... I'd gladly offer both my kidneys for such a glaringly obvious improvement to the sound of my humble speakers and listening room.

I didn't read enough to find a price, but I had a suspicion they'd be more money than a decent amount of some useful acoustic treatment.

I'm clearly in the wrong line of work.

I read the FSA's Brexit consultation documents at work the other day and thought it was bizarre, but this paper is undoubtedly the weirdest thing I've read in a long time.
The placement was particularly fantastic - small wooden discs that just sit on the floor in front of the speakers, so you, your kids, friends, pets etc can repeatedly trip over £thousands worth of precious little wooden discs, mess up their orientation and ruin the room resonance.
What I'd really like to see next is a similar "scientific" paper on the effect of placing one on top of your mains plug / speaker connections as per suggested placements 5 and 6.
Can't wait to read Hugh's review in a forthcoming edition of SoS :bouncy:

From the manufacturer's website:
A simple test by yourself or your clients is to hold the disc with the Chinese logo up or down in one’s palm and feel the weight. Flip the disc over and weigh it the other way, you will feel the logo side down is heavier then the other way. Why?
This is crazy, nothing is added, same disc. There is an energy flowing through the disc to your palm that is enhanced within the ebony. The energy from your palm is the aura of your body that is reacting to the disc energy.
For a male human the aura flows out of your left hand and flow towards your right hand, while for a female its the other way around. The disc is not as simple as it looks and there is a complex process involved in the making of it.

I'm the first to admit I'm far from experienced, but how do people fall for that? Sounds like a pretty good scam.

you've all totally missed the point as usual...

You simply place 3 disks on any of your hifi equipment (as the technical paper quite clearly states) in a triangular pattern. When this disc is excited by any external acoustic energy, it will resonate throughout the entire audible spectrum, thus overriding unwanted harmonic distortions and at the same enriching the musical reproduction

Seriously guys, if we were all like you, the human race would still be living in caves. You have to push the envelope, and not be blind to such amazing technical advances.

I'm in and ready to hear a wonderful change in my Hi fi system.

The same way we fall for all others: a strong wish of something to be true, weak skills in how to distinguish what's true or not,and sufficient arrogance which does not allow you to improve them..

Pah, you're an embarrassment to the audiophile community. Who cares about the audible spectrum?
If it doesn't work all the way up to 90kHz then it's not going to be of any benefit to my supertweeters or 192/24 recordings.
May as well be using standard mains power leads :roll:
