ESP MusicCord

[Robin Ruscio]

Yes it can.

No scientific research article would explain away any discernible effect testers are reporting in absolute terms. They would estimate the effect that "suggestion" is having on the outcome, or discuss it the limitations of the study.

 

[Robin Ruscio]

There have been several explanatory posts.

Where?

 

[JimmyM]

Testers aren't reporting diddly in absolute terms. Every single testimony has been "I could hear a difference." That isn't the least bit absolute.

Read the thread from the beginning if you would like scientific explanations. It's in there.

This is a case of your brain tricking your ears. If you know the ESP cord is being used, your brain will tell you it sounds better.

Not in my case it's not.


No I happen to very sensitive to tonal change. Whether it's good or bad.

If something sounds good or bad to me tonally. At the end of the day discernment works very well for me.

I'm just being true to subjectivity.

Where?

In this very thread.

 

[Bob Lee (QSC)]

Not in my case it's not.

But how do you know?

 

[Febs]

Where?

Start with post #29. There are others.

 

[Mark Reccord]

I'll dissect the damned thing if you guys help me pay for it.

 

[JAUQO III-X]

But how do you know?

Cut it out Bob.

Just like you know the sound difference in your power amp from some other brand.

Conclusions

To many in the engineering community, blind ABX is an accepted experimental design. Using the blind ABX protocol, we failed to hear any differences between an assortment of generic power cords and Nordost Valhalla. Therefore, we cannot conclude that different power cords produce a difference using the blind ABX protocol. However, we also cannot conclude that there are no differences. We simply failed to prove that differences can be detected to a statistically significant degree using a blind ABX protocol.

John Johnson, who comes from a scientific background, suggests that if there are differences between cords, they appear to be so subtle that a blind ABX test cannot discern them with small numbers of participants. Failure to discern them could be due in part to the time it took for cable changes, and the possibility that accurate auditory memory is shorter than that. It may be necessary to switch between cords in a much shorter time.

Unfortunately, as John notes, we don't know of a way of accomplishing fast power cable changes, since, unlike interconnects which can be simply switched between A and B with the equipment all still powered on and playing music, changing AC power cords requires turning the equipment off, switching the cords, and then powering them back on.

The test was a grand and noble experiment at best and a bust at worst. Make of it what you will.

There is some on in this thread who is very vocal about not liking the ESP power cord.


In the near future I think they will have some serious explaining to do

 

[JimmyM]

I have great ears too, and I have proven to myself many times that my ears can be tricked. Realizing that your ears can be tricked is the first step to developing great ears.

 

[Bob Lee (QSC)]

Cut it out Bob.

My question is legit, Jauqo.

Just like you know the sound difference in your power amp from some other brand.

What sound difference would that be? If an amp of another brand is accurate, it should sound the same. That's what power amps are supposed to do.

I tot totally agree Jimmy.

No one has been finding fault with the cord, only with the magical marketing claims to support the lofty price.

Bob has said many times that if a power amp is designed with the goal of an uncolored sound as possible, that they will have the same sound. QSC sells power amps based on reliability and fitting the needs of the customer, not telling us they sound better if they don't.

No, Bob I know it was legit.


Do you feel that your power amps can make a rig sound different from another brand power amp?

 

[Robin Ruscio]

In this very thread.

I just reread the whole thread- I don't see any concise explanation.

Can you lay it out for me or paste it hear?
Please? I'll read it carefully.

 

[Bob Lee (QSC)]

Do you feel that your power amps can make a rig sound different from another brand power amp?

They might, or they might not. If the other amps are accurate and both are suitably selected for the situation, there's no reason to assume that they will sound different, and it is actually likely that they will sound the same.

That could only mean Jauqo is going to try to get the owner on here. Or it means we're going to get hit with a class action Either way, the burden of proof is on him, so I'm not too worried.

Wish I didn't have to go mow the lawn...this is the best thread all year!
