Tantalum Resistors...What's So Different ?.

[mrfeedback]

Tantalum resistors are used in some very high end gear.
Apart from the cost, what is sonically different about these resistors from personal experience please ?.

They have what's best described as a warm sonic signature in my experience.

Compared to 0.1% Welwyn metal films in the same application (in series with the signal path), the subjective changes are less bass, a smoother less detailed (but more enjoyable mid range) and a slight rounding of edge definition at HF. In short, they can help things sound less clinical and a tad more enjoyable on bad recordings - I guess kinda like 2nd harmonic distortion.

Thanks Raj.
Does this describe BB QP experience ?...anybody ??.

Interesting. Almost the entire opposite of my impressions They are obviously abit warmer than say, Caddock, but your descriptions seems more appropriate for carbon resistors than tantalums. Then again, it's probably essential to involve brand particulars. My impressions are mostly based on Shinkoh.

I got these 1W tantalums from Hificollective, no idea on the manufac. Bear in mind I am comparing them to the lazer trimmed Welwyn 0.1% types. No burred edge on those Welwyns so they don't make as much noise as conventional film types when they pass current.

I compared the AudioNote tantalum to Riken carbon in the cathode bias in my 5687 tube linestage. the tants has a more sense of air around the high notes where the carbons sounded fuller and rounded. the tants give the impression of cleaner lines between the mids and highs, but a tad softer in the bass department where the carbons fare better with firmer and richer bottoms. at the end of the tests, i decided that the tants are sounding too 'hi-fi' and the carbons remained in the circuit.

Threads and much discussion on this forum.

Not sure what you mean by this ?.
Two saying subjectively less bass and conflict of opinions in mids and highs ?
