Default Resistor Sound Quality?

Hi! Noobie here with question about resistors.

I have read with much interest in the Blackgate cap threads and the sound diferences they made. I won't go much further into that!

Those BG threads now got me wodering if there are any BG equavelant for resistors? I mean audiophile grade resistors? if there's such a thing.

Or are all 1% metal foils resistors just the same(in terms of sound to value)?

If there are so called audiograde resistors available, what are your prefered brands?

Thanks for enlightment.

Plenty info here...
Search for vishay, caddock, holco, dale, riken, roederstein etc

Thanks float!

I did a serch with "resistor" but came up with many topics and none tittled as such.

Now that I know the search word......

Carbon composite resistors are known by audio-, guitar- and vintage people for their very clean and natural sound.

Composite resistors differ from film resistors in that they consist of a little tube with a composite carbon resistor material inside. This makes the resistance, so you only have a few mm (tenth of an inch) of material in the signal.

A film resistor is made by carving a channel into a carbon (or metal) film on a glass or ceramic tube, resulting sometimes in meters (feet) of material in the signal! Also a film resistor always has inductance , composite resistors don't.

Allen-Bradley is the brand to look for. They are far less expensive than the brands mentioned above by member float.

Thanks klitgt,

I went to purchase some TKD resistors, and tried them out in the output stage of the NAD PP-2 phono stage. The results are good.

I am now wondering if I do a little bit better if I mod the input resistors as well.

I did see the A-B resistor in store. Worth a look.

The store was also showing me some Kiwame resistors, saying that they sounded "sweater at the top end" conpared to the TKDs.

Anymore recomendations?

You should also be aware that carbon composite resistors are unstable and drift upward in resistance value over time. They should not be used where 1) they are setting critical bias levels and/or 2) where you want the equipment to operate consistently for a long time (years).

I think the "classic" amp guys prefer them mainly because that's what was used in the original circuits they are repairing or duplicating and they want to duplicate the "sound" of the original.

I'm in front of a little dilemma : I can get either some metal film Tyco LR resistors or some Vishay metal film.

I assume that Vishay are better in the signal path aren't they ?

Dear Sir,

please have a look at my personal realization and you will understand !!!

Carbon comp :
1) kiwame ( lush sounding - the best ( to my opinion ! )
2) riken ( taut and three dimensional but very expensive )
3) kamaya ( very good but 5 to 10% tolerance )
4) Ohmite little devil ( see kamaya )
5) morganite ( pleasant sound - tend to drift !! )

Metal :

1) roederstein ( tight 'n' fast - a little thin )
2) Holco ( very fast - "metallic treble )

To my opinion KIWAME resistors are the overall winners.
