I agree
I agree with your last statement Bootleneck. This hobby is indeed full of rich learning curves. However since 1988 when I first got into audio as a way of getting more out of the music I listen to, there has never been a time when I have not heard a change either for the positive or negative when trying new cables or components. I agree that measurements are a useful indicator of some possible aspects of performance but never all of them. To many variables exist to ever be definitive all we can hope for is a consensus based on both subjective and objective sources.
I think Deafcats link to the ( independent )test done on a Virtual Dynamic power cords is very interesting . They found a measurable change when using a stock cord and then the Virtual Dynamics cord. I have tried these but their design made them very hard to use. They did change the sound and for the best in my setup, but proved to be to hard to install fully so I stuck with what I have ( three thick Solid core cables as wide as a hose pipe going into a plug and not bound together ).
I would certainly be up for blind listening tests and have taken part in them in the past, but, as has been stated, the circumstances would need to be ideal for there to be any overall value. The tests would need to be conducted as in a scientific experiment, and with controls in place.
Placebo effects. Yes this might be a factor some times but I would venture not in the context of my test. At all times a difference was heard and with the Nordost it was not subtle. The differences between the Audience and Analysis Plus cable were mainly heard in the Bass as other areas of performance were similar, except for those areas noted.
I would love to be able to invite some of you guys over to try all this out but as I live in Northern Ireland I can't do that, which is a pity.
It is a fasinating thing how different people listen and I would love to do some work into this as it baffles me how some can hear somethings and not other things.
I have over the years done blind tests on customers in the shop. I have asked them to tell me what they have heard, but not told them what I was doing and certainly not what to expect. Most of the time differences have been noted and sometimes with greater effect than with others but most have heard something different.
I will illustrate two of those times.
Shanling first versin top loader/valve CDP (I can't remember the model). Got a lot of good reviews. We brought one in and after a lot of run in felt very underwhelmed by the sound from it. We thought it must be faulty. However I took it home for one last listen and got a very good result from it. It took me awhile to work out how. The reason was the platform it was sitting on was different to the ones used before. This was a Clearlight audio RDC platform. One of the rave reviews it got, was from a reviewer ( David Allcock. What happened to him ?) who happened to be using Clearlight Audio racks (similar effect to platforms). I took the player into work,let it warm up and played it again. Several collegues listened and said as before not very good. I placed the RDC platform under the player and did not let them see what I had done . They all heard the sound improve and massively. A custoner/friend who used to be in the trade years ago while in also heard the same and further more we actually found out that it sounded better held in the air (though not as good as on the RDC platform.) I have never before found something so fussy about what it sits on. Now if Magazines today were what they used to be many years ago perhaps David Allcock would have had the editorial space to discover and convey this info in the review, something he did not do. Would have saved some time, but taken the fun out of it.
Second time a mains lead. The TCI BOA Constrictor. This lead is certainly one of the best at giving a massive boost to the performance of any type of kit (system and kit tonality matching is important ). This is blind, deaf man on galloping horse noticeable i.e not subtle. I did cable swaps for a customer without telling him what I was doing and he jumped out of his seat in shock at how big the sound change was( this wasn't even in a demo room but on the shop floor ( so less than ideal acoustics etc). I had the same effect in another customers house, first time he had ever heard such a big change in sound (this was on A Wadia 861 Basic ) and all from swapping a power lead ( Wadia don't believe in power cords or mains filters ).There can be no placebo effect if people are not made aware of what you are doing if anything at all. If you just make the change.
I also feel that group listening is not advisable much better to test things on each listener so they can't be influenced in any way. You know peer pressure etc.
I know this will not convince the hardened skeptics but this is what has happened and only a few occasions out of many, both in my system and elsewhere.
The world used to be flat until it was proved to be round ( funny how JOB new that 1000's of years before modern man did. But thats another topic ). Just try and have an open mind. Even if we can't say why something happens as a scientific formula still doesn't mean it does not happen.
