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.

I’m sure everyone would agree that assessing sonic characteristics of parts in a complex audio system is extremely challenging due to component interactions, but here’s my experience.

Shinkohs and Riken Ohms are nice, but just too colored, in a nice way, to use more than just a few. Have tried the old Holcos, but despite added clarity, they were a little thin sounding in the system I had back then. The Dales are natural sounding as are the old Resistas, but neither of these are as transparent as the naked Vishays.

I think the resistor of choice is the TX2575. There may be some ultimate limits even on these. After swapping in almost 80 of these in the signal path of my 2 hybrid tube amps, 60 in the crossovers, and 70 in the phono stage, I had to put 2 Resistas back in to restore a little more midbass/lower mid-range warmth (the Dales would have worked equally well). That’s all it took. Sadly, I did lose just a touch of transparency.

There are always some tradeoffs. Everyone has there own preferences. It’s really amazing (maddening?) how much changing only a couple of parts can dramatically change the sound of a decent audio system. I’m hoping to be done with all this soon!
