AN Niobium versus Tantalum resistors?

Based on the HiFicollective website, the AN Silver Tantalum resistors are more than twice as expensive as the AN Niobium resistors.  In the audiophile world, the price of two of them to use as series resistors in a shunt type VC should not break the bank.  They actually do sound great in my buffer - a touch of body and glow.  My Khozmo passive that uses Takman REY metal film with two zfoils in the series positions sounds very "clean" in comparison (when used with the buffer).  Maybe I should let those break in a bit more before judging, however, the Amtrans AMRG resistors in my Hattor passive sound just right when used with the buffer.  The only way to figure out what you like in a particular application would be to actually try them.

obviously there is reasonable sufficiency... sound is affected by any details, resistors are not as noticeable as capacitors, transformers...

I would have bought Vishay for myself - and forgot ...

 in the end you are the chef and season to your own taste..

Yes but it is like asking the comparison of two of the same herbs - I had this problem recently with oregano. One brand was so sharp and bitter I could not find any place for it whatsoever. I think its possible to talk about the intrinsic qualities of a component irrespective of where you put it, like comparing 3 oregano on their own.

Decided to try Z-Foils on the input signal coming into the amp, and then Niobiums in the feedback position which seem to exaggerate the color of whatever is used in it. AN is finally sending them my way.

As for silver Tant/Niobium : I cannot stand silver or rhodium in my system because I like the warm fundamentals which always seem to vanish with the slightest rhodium component, so I am fearful of trying these, but I heard they may be different. They are expensive to try.🤔

well. it appears you have taken the plunge. Will be intrigued when you report back..
