I'd have to say,it makes them look a bit better. But the science behind it is as bad as the seizures he gets in the intro.
Reminds me of the godmen, Indians air on their TVs. He's using same tactics, making it appear as if he's giving you some kind of true, undiscovered scientific knowledge.

Meh ... these days people even sell their soul just for click counts, let alone just "screwing" around, no big deal.  :-DD

That was one of the poor man's brain mounting screws. Now he has a whole brain loose instead of just the screw. ;D

I just kept watching, wanting to find what little gem came next.  I was not disappointed!  This clip just kept on giving.

Just imagine, matching up tweeters can be as simple as torque matching their mounting screws!  I've been looking at things all wrong.



What's scary is that there are so many ready to believe this stuff.

What disturbs me most is using a countersunk screw head where the bearing surface is clearly flat.  Not good engineering practice.

I never saw any instrumentation data either before or after that proves it did a damn thing - either good or bad.

I loved the line "resonant energy can't escape from the steel screws and builds up".

This might actually work sometimes, if the speaker is loose or the mounting surfaces are uneven. 

But he missed a fantastic audiophool opportunity by not discussing the audio merits of various drive types.  We all know that square drive is good for older pop music and things like Lawrence Welk, while Torx drive is good for hard metal rock.  I'll leave you all to guess what is best for classical music.  No question though that the star drive (ala VW) is the best for Wagner.

That guy must be a troll. Look at his other videos.
Painting some conductive goo on RCA connectors and vacuum tube contacts, sanding the edges of a CD for better audio because "diffraction". In another one he says that stranded wire is not good for speakers because each strand has different resistance and that means that each strand delivers the signal to the speaker at different time and that makes a resistor.
He makes a video about transformer modification on some player, only to discover that it has a ferrite bead on mains cable, so he doesn't need to do the mod after all.

Homeopathic audio electronics. Did you know that if you swap parts and then shake your device north to south it will work better?  Why he hasn't done that video is just a lack of imagination.

He should have used the screws on a very good and expensive loadspeaker, played on for a weak, and then moved the screws to a cheap and nasty loadspeaker, making the nasty speaker into a audiophile dream.

In the presence of changing magnetic fields eddy currents are induced within conducting materials, even brass.  Imagine how that may offset the delicate balance of the speaker cone geometry only audible by the most sensitive audiofool; especially those whose eyes and ears track correctly.  What is a devoted audiofool to do with everything like EMF, and the earth’s magnetic field subverting the true sound that is almost within grasp?  Maybe ceramic fasteners and little stands to keep the special speaker wire off the floor seem to help them from going googly eyed.

But brass is significantly better conductor than iron or steel, so eddy currents are more pronounced in brass screws.
This guy is clearly working for the Big Brass.

Thats what I was thinking. A "Sound expert" cant make a video that doesnt sound like garbage, doesnt speak very well for his credentials.

Next will come the screwdriver type you should be using to drive the brass screw,  torx vs philips.

I'd say there is way too much oxygen in his listening room. Should try pure nitrogen for a cleaner, purer experience!
Was it really supposed to do that?

You may be on to something here; but it probably is lack of oxygen to his brain.  However filling his listening room with pure nitrogen with him in the middle might get him a well deserved Darwin Award

I've often speculated that dipping audiphools in liquid nitrogen overnight would improve the signal to noise ratio immensely and make listening much less taxing as well as more pleasurable.

At least it is "oxygen-free", which seems to excite them!
