What’s your vote for the most ridiculous, overpriced, and useless tweak?

The effect of this 2 generators audible from my speakers is more clarity and a less congested sound between the speakers ...After all my other tweaks this is a cherry on the cake and very audible in near listening field and at a normal distance listening in the room also...

I put few days ago the first generator near a speaker... adding a second one nearer to the second speakers changed the relation between the 2 speakers for the best...One of my speakers is near a wall the other near a door, the relation between the 2 is special and not ideal... This peculiarity makes it easier to spot changes in the imaging and soundstage for the worst or for the better...

I have a Blu Ray player with a USB port. Can I plug the device into that USB port? Does the Blu Ray player have to be turned ON or is there a “trickle current” as long as the player is plugged into the wall?

There are four obvious technical errors in the following paragraphs from the Von Schweikert technical description of the MasterBuilt Ultra Speaker Wire. Grammatical errors don’t count. Get all four right and win a prize."

It is hard to narrow errors to only four. Would they be called "technical" or "just errors" is less important.

It reads like someone from the Department of Transportation tried to make a joke. Electrons making screeching noises when jumping curbs or colliding with other vehicles. Some of them carrying heavier loads, some lighter, which makes braking performance different.

I wonder how far would this go, how much would it cost, if someone approached the company and asked for upgraded cables in a Walkman. Let’s say, whatever little wire is there to be upgraded. Maybe, while they are at that, even ask them to design a better headphone jack. What number would it be for that custom project? $10 000? $117 000?

Glubson, I’m afraid that’s not even close. 

Geoff I know that an antenna need to be connected electrically to the gear...Mine is only connected to the shungite stone or the tourmaline stone at the center spot of the printed connected original antenna and perpendicular to it...I cannot explain why my perception of the sound is better with....you are the physicist...Some would say placebo, it is possible ….I dont know...
