And just like that, Amir busted another cable myth. Also nice vegetables you got there!

I see that AQ is still putting batteries in their cables for "dielectric biasing". Back when they sold "Kilimanjaro" cables, the batteries straight up leaked DC into whatever you connected them to. This caused all manners of audible effects which led proponents to claim that these cables "made a difference".

Is it legal to have a lottery that cannot be won? If no, we can prove in court that cables (at least the ones under test) cannot be distinguished.. That might sway a few hardcore believers..
It can be won. Until we test everyone, there is still the possibility that there is that one super golden ear that can hear the difference. Unlikely that such a person exists, but still possible.

Sure, but the heat death of the universe might come first ;)
Depending on how the test is setup and the number of trials, yes obviously.
But if you go for a 10 trials run for example, the math says that a random answerer will get all correct answers 0.1% of the time.
Now, repeating that test or doing 20 runs is another story I agree.

It's not the batteries that are the problem. It's the battery indicator light for knowing when you need to change them that is the bigger issue.

If the DBS system is such a game changer then you should be able to hear when the batteries ran out of charge.

You can't make people engage their critical thinking portion of their brains.

I found some generic cheap cables have only a single spiral wrap of less than 100%. How much is you can see the white through it. The spool of Belden 75 Ohm stranded cable I bought has a double wrap. No white even when bending and a much thicker jacket. Of course RG-6 will have a braid over foil and be pretty darn quiet. Just a pin to terminate in an RCA.

2.3k for a cable. Well for $2300; New Schiit DAC and preamp, new Parasound amp, JSL tone control, built new crossovers, and enough to pay for the all-in-one PC as a media server. Nice firm RCAs, 1 foot. And of course a Belkin USB cable as it measured better than $15 Monoprice.

I had a length of special made S-Video cable from Blue Jean. Tiny, but 75 Ohm. Never got around to trying it out. Worked for 40 fet of video, so would probably work for 2 feet of audio.

If you conduct the test enough times, someone will guess correctly by chance.
Sure but the results have to repeatable, not a one shot lucky guess.
At least an 80-90% average. ;)

Depends upon the number of trials you allow. Whether individually or collectively. Remember the 5% significance means there is less than 5% the results are a lucky guess. Or to put it another way around, done a 100 times, you would expect this by chance 1 of 20 times.

Sure, just saying you couldn't allow some rectal golden horseshoe to walk in, sit down and with one 1/10,000 lucky guess, stand up and collect the million. He'd have to back it up.

To flesh out a scenario. Suppose I had each person trying to claim the prize choose 20 times. 15 of 20 correct is slightly less than 5% probability of guessing. If I gave this chance to 100 people, I'd expect 4 or maybe 5 to just happen to get 15 or more. I'd not put significant money on such a chance.

If I raise the bar to 17 of 20, then I'd expect someone would get this accidentally about once per 400 people. Alternatively requiring someone to score 15 of 20 and then score 15 of 20 again comes close to also being around a once per 400 probability.

In Richard Clark's $10,000 amplifier challenge, to claim the prize you had to score 12 of 12 and then score 12 of 12 again. Supposedly over the years a few thousand people took that test. No one claimed the prize money. I believe the odds of getting lucky 24 of 24 is just under 1 in 17 million. 20 of 20 is roughly a one in a million chance.

If, by chance, someone aces a test that is most likely not possible then:
A: The same individual must do the same test again to be sure.
B: When that one is also beyond average luck then the test should be checked with meters.

When A and B are O.K. the test is valid (for that individual), Good luck with testing interlink cables. Never going to happen unless the test was rigged or there was a give-away (such as a different sound of a relay or something else)

Better hope the listener is not a Terry Pratchett fan as they will know that million to one chances come off nine times out of 10!

I hit the lotto 3 times the last month. For $2 and $2 and $2.
Well, in this case there are no consolation prizes.. It's all or nothing

But it would definitely be interesting:
- base price of 10K
- ask for a 10$/€ entrance fee. This will be added to the price money
- if you win, you will win half the prize money. The rest will be donated to a charity of ASR's choosing
- every year half of the prize money will be donated to a charity of ASR's choosing as well, while maintaining the 10K base price

I am afraid the cashbox will only hold 10k all of the time.

Cable believers will:
A: know they are right and don't need to prove it.
B: Don't need the prize money, they rather spend it on cables as they have plenty of cash to spend.
C: Don't want possibly to be embarrased should they fail the test.
D: Think the test is rigged anyway.
E: Most don't believe in AB tests as they have been known to be inconclusive thus the test is wrong.
F: Have no intention to travel for this
G: Claim the test setup is flawed, uses not revealing music/gear
H: Due to stress 'lock-up' and can't do what they easily can at home.
I: the wrong cables are used in the test.
J: Despise Amir and don't want to meet him and certainly not be fooled by him.
K: Are convinced measurements say nothing.

I may have missed a few other reasons not to take the $10k bait. :)
