Top resistors


Many threads with opinions on boutique coupling capacitors, but very little consolidated information on the sonics of resistors. Anyone care to share their thoughts on the attributes of their favorite brands & types for specific tube and SS applications? How much of a difference does a good resistor make?

My interest in the topic increased after recently installing the latest Texas Components nude Vishay TX2575 in several SS and tube phono & LS components. This was a proverbial "Ah-ha" moment-- a stray resistor dropped into signal path here or there, surprising with an improvement that equalled or surpassed the impact of a switch to a top coupling cap like V-Cap or Mundorf.

There is a lot to consider in my opinion when choosing resistors. Is much more than just making sure they will handle the power.
When it comes to noise, there is nothing better than high quality wirewounds such as Dale RS or Mills. You also want to use a larger physical size in areas that can be prone to noise. No problem using a 5 watt where a 1 watt would work. It can make a difference.
There are certain applications where a certain type of resistor is better suited. Unless going for a vintage sound, I stay away from carbon comps anymore. They are just not reliable enough and can drift in many applications. I wont even use them at grid stops.
There are some very good metal films available today as well as some decent carbon films.
Resistors can make a sonic difference depending on how and where they are used. I would certainly not used sand cast resistors in the signal path just as I wouldn't place a carbon comp in the power supply.
