Metal or Carbon Resistors - Which is better?

@lalitk 

Supposedly the film resistors are better, but I doubt I’d hear the difference in a passive preamp. If it’s an option, I would try wire resistors, but then again, with the preamp being passive.  I’m not picking on passive preamps, but they so many fewer parts, a few better resistors might only make a difference on paper.

All the best and let us know what you decide.

For some passive linestages, the resistors are almost the whole game—they have a few switches/selector, and attenuation means a stepped attenuator or relay switching of different combination of resistors.  The right choice is important.

There is a website that reviewed resistors for a passive attenuator and it concluded the Audio Note 2w silver tantalums were the best sounding by far; unfortunately they are so expensive it isn’t practical to use them for all steps in a stepped attenuator.  

@lalitk please let us know the specific use. It is to load a stepped attenuator? Khozmo attenuator? Shunt style stepped attenuator? Omron relay based Shunt type? Thanks.

Nude Vishay ZFoils are wonderfully resolving, quiet and still pleasing to the ears. They do less editorializing than the other resistors mentioned. You could place Audio Note 2W silver tants in the shunt position.  

Potentially even better is to avoid this question by using the Tortuga LDR based “The ePot.V4”system. Perhaps the best sounding attenuator/control center on the market.  I am just not exactly sure what you are up to.
