Resistor Sound Quality?

They are identical: Vishay exclusively manufactures the foil (nickel-chromium alloy like many metal film and wirewound resistors), everyone else simply does the final manufacturing of the package including the foil etching for the pattern and final trimming. Vishay would have tight specifications for the final assembly too; it's a highly engineered product.

I don't much care for the 'naked' Vishays; they look flimsy and lack the protection and damping of the packaging.

Damon,

Thanks for the info.

Though I have tried and still have some Boutique resistors like Caddock (pre amp), Welwyn, Isabellenhütte
Manganin foil types (crossovers) and PRPs all throughout my PearlOno, to be honest, I strongly do believe
I don't hear any differences between (reasonable quality metal film) resistors at all.
Nevertheless, I really do make sure to use lowest tolerance values esp. in a RIAA network. I also select
and match them in pairs.

I am currently of the mindset that it matters most in low level stuff, and even there, only in ey signal positions. In power amps, I would only look at gate,feedback, and source resistors. Oddly enough, I just built an amp where i prefer the Vishay Ns series over Caddock's. Caddocks distorted the sound in a more unpleasing manner than the Vishay NS. Good thing about major brand parts(vishay,issabellenhueete,others)is they tend to be more consistent and have lower tolerances.

I can hear differences between all resistors.

I know why some people can not. If I tell why you will not believe it. 😀

Did anyone tried new Audi Note non magnetic Tantalum resistor?
Just curious how it sounds compare to old AN resistor and even with shinkoh.
The price AN new resistor is too expensive for me so I won't dare to try if I haven't know how the sound signature.

Cheers,
Erik

But everything is magnetic to a degree, or do you mean ferromagnetic!
As music is AC I still am finding it hard to understand why magnetic components are bad? yet are used extensively elsewhere in the world in critical analogue circuitry with no problems and no concerns... curious:scratch2:

Tubes, transformers, speakers, microphones, all apparently are exempt from this fashion-driven phobia.

As long as no one bothers to do ears-only testing of their hypotheses, you'll always be reading nonsense like this put forth with great confidence. But ears-only testing is not likely to give you means of sounding like an expert on internet forums.

Non magnetis is allways much better. Original Shinkoh was fantastic . Modern Shinko is crap.

Concerning magnetic or not for every component include resistor, I did several test on resistors including AN magnetic (not sligtly magnetic as advertised) and also magnetic beyslag and kiwame.
AN magnetic tants still sounds better compared to Dale RN or Takman carbon (both non magnetic) and I can't detect any distortion in audio reproduction.
So...magnetic or not...as log as it sounds good...I don't care either.
I just want to know if someone have tried new AN tants resistor (I suspect they got from new manufacturer) if it sounds better than old AN tants or even Shinkoh.

Cheers,
Erik

I Know, I have asked several (thousand) times what the mechanism my be that causes magnetic components to distort the waveform, but to no avail...
One wonders whether I should worry about the steel case my amp is in!
The haemoglobin in my blood, possibly could have an effect if I am in the same room as my system when playing...

Use a magnet to determine if your resistors (and connectors) are 'magnetic or not. Most of the best resistors are NOT magnetic, but a few, like the older RESISTA devices are slightly magnetic and still sound good.
Some of the finest quality resistors that I have in my inventory, you know: gold plated leads, glass cases, .l% to .01% tolerance, can sound LOUSY! At least that is what I determined went wrong in a preamp prototype that I made with them. The preamp sounded lousy, even though it was made with Levinson JC-2 modules, primarily. I do know that they have 'magnetic' leads, but that is all that I can determine what is wrong.
Perhaps I should try again with these devices, but I have too much to lose to just put them in any critical audio path.

Metal film, most of the stuff I do is commercial and not my designs, but I do tinker a bit, though get very little time as I have spent most of the last year copped up in a hotel room, while working on site (doing PCBs for noise cancelling kit), so lots of 0201s 0402s. in fact the Tant nitride resistors are available in SMD, good for humid environments.
John, if there is some change or degrading of the sound there must be an effect, and it should be measurable.
