Mr Wurcer, I suggest you to buy pair of WBT Nextgen 0114/0210 pair of RCA connectors and use them in phono preamp input. I was skeptical, but they are close to no-connectors and give more details and lower noise than lower grade but decent gold plated connectors.. My IC is 1.5 Euro/m good quality twin-ax microphone cable. If they are good enough for recording studios...
Connectors are more important than cables.I know that it is against theory, but they are worth every cent.
Buy? How can you expect someone to pay money for something they don't believe in? Particularly, when the item in question appears to be grossly overpriced?
Richard, go back to the link and look at the density of flux lines.So? If we use the flux lines in a wire, we see the density varies and is least dense at the outside of the conductor.
For DC, within the wire, the flux is zero at the center of the wire, rises linearly to a maximum at the surface of the wire, and external to the wire, it has a 1/r relationship.
It is important you learn this simple aspect of magnetostatics.
Do you mean to tell us that there was NOBODY at LLNL who understands E/M theory??Physicist, yes. There were not maybe 6 EE who used calculus on a regular basis.
I find that difficult to believe.
Richard, it is not MY assumptions we are discussing. It is actual E/M theory as taught in the second year of undergrad.I am sure you are [correct] for the assumptions.
As well, it is not MY models we are discussing. It is the actual understandings of the magnetic field as per those dead guys Ampere and Maxwell.
If you choose to claim that both of those dead guys were incorrect, then provide us some semblance of proof that they didn't get it right.
But, I am more interested in how inductance is created using flux density in a wire to establish a theory for skin-effect.
Inductance is NOT CREATED. It is the relationship between the current driven into a system and the total amount of magnetic energy stored within the system.
I fear that you will never be able to understand the explanation if you cannot accept the validity of maxwell's equations, specifically Amperes law.
Go to page 27 of this slide presentation.

For goodness sake Richard, learn this stuff.

No, I am listening to the music and hear more low level details and lower hisss , firmer bass and I do not care about measured difference. It is DIY AUDIO forum after all.But I am not crazy to spend my money on snake oil things, but WBT connectors are serious audio components.Expensive, but much more important than higher grade resistors, capacitors, interconnects etc.Of course you have measurements to show the lowered noise floor?
NO. Textbook theory NEVER states that for typical home wiring. And, it never states it EVER..and I already said what happens, also, in typical home wiring.
text book theory would say the flux is evenly distributed across the whole cross-section.
E/M texbooks state that ampere's law defines the flux distribution within a conductor carrying current. And that for a cylindrical conductor and DC current, it matches that which I've described, that which DF96 has described, as well as what every E/M texbook I've ever read describes.
You will find that making up your own version of E/M theory on this forum will not bear fruit. Too many here actually understand this stuff.

Sometime, a small risk is useful to gain our experience.Buy? How can you expect someone to pay money for something they don't believe in? Particularly, when the item in question appears to be grossly overpriced?
Mr Wurcer, I suggest you to buy pair of WBT Nextgen 0114/0210 pair of RCA connectors and use them in phono preamp input.
When I get a chance I'm rewiring my TT for differential and using Neutrik mini-XLR's everywhere. I've had excellent results with their RFI resistant XLR technology.
I'll second Bill, noise is a measurable physical phenomena not a subjective sensation. So, measurements?
BTW does Nextgen market their stuff with garbage physics like Eichmann?
I wish someone would make a magnetic field line demonstration for a flat coil. I still have not seen a graphic showing what the field lines of a flat coil should look like.
When skin effect dominates the impedance of a wire, is the current density profile through the wire the same at the crests as it is at zero-crossing? Even though the di/dt are different?

How about a laugh - original on diyaudio!
"There's another benefit for using a fully differential amp. That is that both of the speaker wire connections are active voltage (as opposed to single-ended where the negative/black terminal is just ground). This means that you have two sides controlling the movement of the speaker itself. [] Using a differential amplifier will have more force on the magnet of the speaker because it's now a push/pull situation. A single-ended amp will be more "loose" in its ability to control the movement of the speaker."
Cracked me up!
Jan
I like it. Its simple, graspable and makes clear exactly what all this push pull stuff is about. Finally, some straight, solid information.
More L8r 😉

Actually that would be difficult with all the surface noise on the LP.
I wonder why Jackson still has so much traction (sounds like the beginning of a limerick or other poem). I went through I think three editions of that book. In those days I acquired about everything that might have any use or advantage, or to see how another author would handle a particular subject.
That said, if you want to refresh your algebra, Michael Artin's book is outstanding.

Okay, maybe you want to take a small risk and send your connectors for Mr. Wurcer for his evaluation, if he would be willing to accept them on that basis. Ordinarily, I would expect him you charge you consulting fees for this, but since you are a forum member here perhaps he could grant you a generous 5-10% discount or something. No doubt, it is apparent that the small risk on your part would be well worth the certain outcome that you will be proven right in front of the whole world. If nothing else, as you say and I think we both agree, you will at least gain some experience as a result.

Sssh, enough people were put out when SY pointed out that about 70dB SNR is the best you can ever get from vinyl even with noiseless records, which don't exist.

I tried Neutrik mini XLR for power supply connections, they are in fact Rean brand Made in China connectors not of the same quality as genuine Neutrik.Very poor gold plating.
If mass storage effect and eddy current is garbage physics , yes. But WBT Nextgen conn. are perfectly built with very firm collet type ground connection which is unique feature with non standard RCA sockets.
For MC cartridge signal level, it is of vital importance.
You are a joker. It is the last thing I will do im my life .One pair of WBT connectors are priced as a hair dressing service in the USA. Blind theory is bad for audio.Some members here pay high prices for some capacitors with zero improvement in SQ.Okay, maybe you want to take a small risk and send your connectors for Mr. Wurcer for his evaluation, if he would be willing to accept them on that basis.

It is hard to describe noise reduction with WBT connectors , but it is not surface noise , but record useful signal garbage noise which masks details.Sssh, enough people were put out when SY pointed out that about 70dB SNR is the best you can ever get from vinyl even with noiseless records, which don't exist.
Free test is direct soldering of IC to inside eq. eliminating connectors.

$15 for a No. 5 here. Probably best to drop it, if they make you happy that's fine. No measurement though?
EDIT - Yowza! $50 each for just the connectors. Yes "the mass storage effect" would be classified as questionable physics.

Well that's good to know. I'm glad that's sorted....
A friend of mine has specialized in Deaf Studies. He's an expert about signing, which makes sense. But he introduced me to a new word: Audism.
OK, Mr. Wurzer. You should be more polite. I am not happy to waste my time with people who are listening to music on measuring equipment screens.$15 for a No. 5 here. Probably best to drop it, if they make you happy that's fine. No measurement though?
As I said , it is Do it Yourself audio forum . Some people belong to other forums.
