So do I.

Where there are two completely opposing approaches, listening for themselves is the only way........and I wholly agree with thinking for themselves, which is why I never take a dogmatic, absolutist approach.

 

what, absolutely never ever?? Wink

People are claiming a substantial change.

To me that is not substantial merely noticeable.  In my book substantial would be going from a £500 to a £1K+,.  Now that could be termed 'night & day' in terms of difference. Wink

Hi,

I believe that the poster is stating a substantial change - better bass, more clarity - surely this is a substantial change. They have not used the word slightly better, or descriptive words such as this. So for that person, the change was quite significant.

Given that you have stated £500 to a £1k+ system change - how does money assure improvement.

I was going to purchase a CD player in the early 1990's - one auditioned was a philips player modifed with  a different op-amp and different transformer. The philips cost approx £200, and the modified player £600 - just for an op-amp and transformer change. Hence - money does not guarantee improvement.

Regards,

Shadders.

You're one of many, recently and historically, to cite partner's ability to spot these 'obvious' changes. Thing is, no-one's ever done it in controlled conditions. So either people are blessed with remarkable golden-eared partners or they're getting subconscious cues. I know which I think is more likely. 

Hi,

There do seem to be two different groups - people who can hear the change, and people who cannot hear the change.

Science in this area of circuit theory etc., has been documented for 2 centuries at the earliest investigations.

For those that hear a change - there are two possibilities.

1. There is a change

2. That the person is succumbing to the palcebo effect (make a change, expect a change and hear a change)

The people who hear a change claim it is number 1 - and always seem to discount number 2.

For these people, there is a claim from many of them that science cannot measure everything, and the change is real.

If science cannot measure the changes that they hear - then an opposing theory intimated as above - that the other half has somehow received subliminally a cue that something has changed can be true.

That is, if the people claim that science cannot disprove that there is a change heard for speaker connections, and science cannot disprove subconscious telepathy exists, then subconscious telepathy is an equal proposition that the other half knew of a change from the person who changed the cable.

So it is quite possible that the people claiming the change exists are prone to the placebo effect, and intimate this to their other half through subconscious telepathy.

This is equally valid since science cannot prove the change does not exists (the claimants proposition) and science cannot disprove others are aware through subconscious telepathy  (my proposition).

There are vast number of people who believe in telepathy, subconscious or not, and hence is their belief as invalid as audio people who believe they hear a change ?

Shadders.

Indeed. There is a difference between what is possible & what is plausible. IIRC, there's no scientific explanation for acupuncture but its benefits aren't doubted by many scientists. Oil companies employ dousers - no scientific reason to do so apart from hedging their bets. Science is more than capable of denying the existence of anything lacking "prove". Many scientists believe in God. My world isn't in black & white nor are most peoples.

There are some forum objectivists who believe that all amps adhering to a certain specification by definition sound the same & that all modern DACs sound identical. Many of these folk don't always practice what they preach: their list of equipment is often the give-away in their sigs.

There are some safeguarding reality checks anyone experimenting should carry out such being sceptical as the default, realising that we are easily fooled & always undoing "improvements" should undo the perceived benefits. I rarely hear perceived improvements straight after doing them but may well do days later - one reason I'm sceptical of DB ABX relying on short-term memory.

This is an interesting slant.

I have had a fair amount of Acupuncture, mostly without much long term success - though I thought science was coming to grips with how it worked.

My father used a well known local Douser to find a couple of wells on their property.........not only did he pin-point 2 wells, but was accurately able to determin the depth (by walking away from the position of the well, and measuring back to this, from the point where the rods jumped back towards his chest).

Hi,

My proposal is possible and probable - equally to the people who claim there is a difference and their other half stating what has changed.

My post was to highlight that people are prone to the placebo affect, and if the other half recognised this, that the recoginition could be due to subconscious effects.

There are reports of twins knowing what the other is thinking in specific circumstances, or aware that an event has happened to the other person, people knowing what someone is going to say before they state it, and people knowing that someone is about to telephone them and then receive that call.

As with some of the examples you have provided - there is no scientific proof - but the placebo effect is provable, and is scientifically recognised.

The topolgy of an amplifier can vary - there are so many combinations of resistors, capacitors and semiconductors that constitute an amplifier - so similar measured performance does not guarantee that they will sound the same, but the hifi reviews i do read - especially a group test, in some circumstances, the changes do not seem too great for similar amplifiers - power houses - with multiple output devices as an example.

With speaker connections - not the cable, just the connection - a hard wired piece of metal less than 2 inches connecting either top to bottom, or vice versa at the speaker terminals - to produce the changes as stated by some people - would have to be discussed.

Regards,

Shadders

It's really no wonder we can't win an argument, if telepathy is a more likely hypothesis than "we actually heard it".

Hi,

I am just trying to apply the open mind approach on what is possible. Science states the change should not affect the sound, people claim it does - so i have proposed an alternative. This alternative is valid and equaly probable - that is all.

Regards,

Shadders.

I was being a touch facetious.

It's feels at times, like being an innocent and frustrated defendant in a court case, where nobody believes their alibi (except for family).

I suspect science probably can explain, but us mere mortals aren't equiped to debate it on equal footing / standing with somebody qualified. Qualified people can get it wrong, and frequently do (that is not having a pop btw).

FWIW I do appreciate your polite, respectful and objective approach.

Placebo effect & expectation bias certainly exists - hence a healthy dose of scepticism helps lessen it. Regarding amplifiers, some will argue that whatever the topology used, if they measure the same, they must sound the same - simples. Many engineers snort at the notion that existing measurement techniques aren't fit for purpose. Some very well-known design engineers such as Baxandall were extremely dismissive of subjectivism. Many speaker manufacturers reject designs that measure well but don't sound that great. One designer, John Westlake has well-honed technical skill, uses measurements to refine his designs but also uses his ears & takes note of his customer's feedback. Sometimes, I wish the world was in black & white!

RE: Correct wiring of jumper cables

Been researching this topic recently with my new Wharfedale Jade 5 speakers. I am trying to find the best way to single wire to the Jade's biwire terminals with jumpers in use. Wharfedale's user manual advices to connect the positive cable to treble terminal and negative cable to bass terminal. This is consistent with many of the posts in this thread, and also with advice given on The Chord Company's and Audioquest's website. However I came across this http://www.nordost.com/downloads/NorseJumperinstructions.pdf which proposes the opposite ie. positive cable to bass terminal and negative cable to treble terminal. 

I did give the Nordost way a shot and seem to prefer this method to the one in Wharfedale's user manual. I wonder if anyone else has tried this? For those currently using the cross wiring method, it's something worth a try, after all it costs nothing other than time.

RE: Correct wiring of jumper cables

Hi there - just curious to know what the tellurium cable was like when u terminated it - amything unusal or just two strands of copper wire? How thick etc? 

Cheers
