Hello!
Anyone has tried to replace ROE resistor with tantalum? What is the result?

Thanks!

The question should include your objective, but I'll try to answer.

I've had experience with the Resistas which were really very nice sounding (clear and with a touch of warmth) back in the day - not sure what Roederstein is making today. The only tantalums I've tried are Shinkohs so my comments are limited to those and they would be my tantalum preference if I were to use any. They are a little sweet and warm and silky sounding in a good way, but still pretty transparent.

Using more than a few Shinkohs would result in a sound that's quite colored as described - not advisable.

"Roederstein" is a brand name, whereas "tantalum" describes all capacitors of a certain construction using tantalum as the dielectric and being polar in nature. I think most Roedersteins are metallized polypropylene or at best polypropylene film types. Anyway, although some commercial products I have read about do use tantalum capacitors in the signal path, apparently, in general they are best kept out of the signal path. So, I would say that any Roederstein that uses polypropylene dielectric would be preferred over any tantalum, in the signal path. The major advantage of tants is small size. If you insert them in reverse polarity or expose them to voltage that exceeds the rating, they explode and catch fire after exploding. This is unpleasant when it does happen. Believe me; I know.

  he is talking about resistors. From mrmory, Rodersteins are (or were) magnetic. Tantalums tend t have a clear hf, but I prefer bulk metal film ie Vishays.

    Somehow I read it the way my mind wanted to read it, and because I never think of "tantalum" as a reference to resistors, even though I use them liberally here and there in my gear.
    Apologies to the OP.

  Yeah but he was asking about resistors
