Popular Post AJ Soundfield Posted July 11, 2017 Popular Post Share Posted July 11, 2017 Why do you need an objective crutch for your purely subjective perception? Not enough to just "experience" it? Teresa and bodiebill 2 Link to comment

I know they do. They might not do it as a ground reference in a proper sence, but they seem to make those spots better. Could this be due to a reduction of anti-statics do you think? The bit I highlighted seems, in my view, to be the cause of all this misunderstanding. Some of the participants in the conversation have put forward possible explanations for an audible change to the signal. But apparently you didn't find a a single one of them satisfactory because they clearly do not reflect or explain whatever expectations (belief) you have for grounding boxes and the mechanics at stake. i find extreme experimentation quite commendable as long as one's attempts at explaining observed phenomena do not go (too far) beyond reason aka science. @AJ Soundfield has been mentioning bias quite often; in addition to visual bias there is also that which comes from reading the propaganda which manufacturers issue about their products and also from reading reviews. In my opinion one should not read reviews before assessing the sound of an equipment for that particular reason.

If you shake a Entreq grounding box you cannot even hear the stones moving inside. Aucharm grounding boxes have loose stones inside, but their grounding box isn't as effective either. So is your theory then that a build up of static electricity in tourmaline (happens even if nothing is attached to it) causes some sort of beneficial effect on SQ? There are much cheaper ways to produce a static electric charge. -Paul DeltaWave, DISTORT, Earful, PKHarmonic, new: Multitone Analyzer Link to comment

As marce says, your equipment shouldn’t be building up static charge because it always has a place to discharge to. (It is the same as if you were always touching grounded metal - you wouldn’t build up static charge either.) So granting that you are hearing some difference, either you are affecting ground loops/noise in the system (in which case, as mansr says, any connection such as a simple wire should suffice; or better still, simplifying wiring in your system to the extent possible and paying careful attention to grounding to minimize any ground, leakage, or other noise currents); or the wire to the box is acting as an antenna and you are indeed changing the sound by actually adding noise. I personally think the first of these (changing ground currents/noise) is more likely in most people’s systems, though of course I don’t know about yours in particular. Interesting! I like the idea that the grounding boxes are changing ground currents/noise! ? Do you think they block them or just reduces them? I can tell you that I always found the grounding boxes to have "similar" effects to a GND-lift. 🎛️ Audio System Link to comment

I am quite sure there are many other ways to make the same improvements, and would love to learn about them. IMO it could be either that the boxes deals with anti-statics or ground loops as mentioned by @Jud. I am interested in any plausible explanation why the grounding boxes affects SQ. Ofcourse it is not likely that I believe in an explanation that decrease SQ since I have very positive results myself! ? Teresa 1 🎛️ Audio System Link to comment

That's is why I have invited disbelievers to this thread in the first place. My only problem is that it seems that I am the only one here that have actually tried them IRL. Based on my personal good experiances in a well isolated setup I just find it hard to believe in theories that decrease SQ or do not affect SQ at all. 🎛️ Audio System Link to comment

Well, so far I've not heard any explanation that makes any sense, except for these boxes acting as an antenna. I don't see why you'd want to inject EMI/RFI into the ground plane of any audio device, but, if it sounds good to you - keep using it. -Paul DeltaWave, DISTORT, Earful, PKHarmonic, new: Multitone Analyzer Link to comment

Ah - that would seem to be an indication in favor of the possibility that what you are hearing is a change in ground or leakage currents. If that’s the case, you might well be able to take measures that are both less expensive and more effective. There was a system topology thread here a while ago that might be helpful along the general lines of simplifying and rationalizing your system layout. And I dare say @marce, @Speedskater, and other members who have a great deal of useful knowledge about system grounding issues could possibly be very helpful if you gave them detailed information about your system, its layout, power connections, etc. One never knows, do one? - Fats Waller The fairest thing we can experience is the mysterious.

No you aren't. You are seeking an objective crutch for a subjective belief, due to unease. You will completely dismiss the most plausible explanation, it's your imagination and instead seek some techno-babble "objective" one due to remote plausibility like grounding etc. You won't test for either of course.

If you look at that comment, who is it really for? It's for AJ and perhaps people who like him. It's not for the person asking questions. No minds are going to be changed or educated with a comment like that. I certainly hear you about talking with an Anti-Vaxer. I have one in my extended family. I used to provide facts and data to this person. I've now stopped talking about it with him/her. I have no duty to continue discussing the issue. Even after the measles outbreak here in Minnesota because of the crusade of an Anti-Vaxer, I didn't talk to this relative about it. I wish some people would take this approach. If talking to someone using what you know to be true, yields results that one doesn't agree with or similar, just stop talking to the person.

Heartbreaking as I couldn't imagine putting my child through that. But here is where our approaches diverge: The person that isn't reasonable, or in some sense of the word may not be totally sane in a narrow context, may need to hear the message, often, from others. Because it MAY click when someone else gives them basically the same information. And yes we live in a society where some amount of shame or ridicule, hopefully, carefully measured out, as stick vs carrot. AJ is not alone in pointing out these alternative explanations. What's left after sound data has been rejected? I don't think he's being a jerk, he's simply left with no other conclusion given the data. esldude and sarvsa 2 Link to comment
