Again, you show your ignorance of modern cognitive psychology research when making claims such as the one above. This is one of those 50% or so of cases where you don't know what your are talking about.
If you disagree, please cite credible cognitive psychological research supporting your claim.
Note: By the way, but the whole idea of 'expectation bias' is audio is an internet forum meme, it doesn't exist. The proper definition of 'expectation bias' can be found by googling the term. It is synonymous with the term 'experimenter bias' and refers to a bias affecting professional researchers, such as those that attempt to measure human hearing perception. It is not a bias of the test subjects taking hearing tests.
I take your point but doubt that was Pavel's intent. There were people who expected not to hear a difference but did and were surprised. I don't find it necessary to conclude they were fooling themselves
I suggest you post that in the thread so it can be discussed.
Don't know about Monster speaker wire. Schematics and other info on the power conditioner both Richard and Demian are credited with starts at https://www.diyaudio.com/forums/the...wtorch-preamplifier-iii-2930.html#post5929120 ...and continues for a few posts over the next few pages of the thread. Its was a fine, serious product, IMHO, not junk by any stretch.
No problem... The correct term is Confirmation Bias (And that's only the first of hundreds of links)
In the case of the two file test, the expectation that there is a difference is created in the way the question is asked... then listeners will hear a difference that confirms that expectation never considering there might not actually be a difference at all.
Let me give you an example from something we did a couple of years ago... One of the local Golden Ears was bragging that he could tell the difference between all kinds of gear. So we rigged up a blind test and played about half a dozen things for him to judge, the equipment was on the table in front of him, but the switch was hidden... He claimed it was easy, picked them all out no problem. Only thing is... the switch wasn't connected to anything and none of the gear on the table was actuall used in the test. He *expected* to hear differences and each time the switch clicked he confirmed it by pointing at one of the units. In fact, he was simply responding to the switch snapping.
This kind of testing amounts to ESP testing and it gets about the same random result as most ESP tests do.

Again, you show your ignorance of research. A sample size of one in an experiment of human perception is meaningless. Not only that, you hand picked someone you were certain in advance would fail the test, which means you had a serious case of expectation bias (and confirmation bias too).
By the way, its not hard to show that humans can be tricked (which is what you did). That is very different from an experiment to find out exactly what a representative sample of a population can hear.

It probably wasn't. He was just asking a question.
Naaa ... I'm getting really tired of this discussion. I'm arguing with a zealot who's already accusing me of bigotry and personal attacks... I think it's time to let it go for now.
Plus, my ride will be here in a few minutes and I need to finish the job I've been working on...
No problem, I'll do it for you, nothing in the rules says you have to engage in the discussion....... if there is any 😉
As long as you understand they make no difference to the sound of your system and serve no purpose other than the asthetic... go for it.
BUT... if the price is too high and/or you expect it to somehow improve the performance of your equipment ... save your money and take your better half out for a nice dinner instead.
Wrong thread, this one is about Lingwendil making lifters for gags or show off. 😀
Will do Douglas - as soon as she's finished the cable lifts! 😉

Dunno. You could try a cardboard box and see if you think the lift it provides makes a difference. If you do think it does, you could repeat the test several times over a few days to see if your results are consistent.
If you do find a consistent benefit and decide lift helps in some way, please describe what you hear that is consistently different with the cardboard lifter in place. Also, it would be helpful if you could post a clear, in-focus, hi-res picture of the cable path and surrounding materials at the point you find the lift beneficial.
There is more you could do to investigate if the lifter is helping and or if physical causation can be identified. Depends if you care enough to do all that or not.

This has turned into another stupid cable thread with the same old arguments.- Status
