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.

Can Anyone help me identify the wattage of Caddock MDN0178 11.75ohm, 2% resistors used in the tweeter section of Wilson Audio Sophia 3?
I'd like to change it for an 8ohm resistor but don't know the required power capacity.

Thanks a lot!
Actually the resistors are outside the crossover system, so it shouldn't change the crossover point. But they do act as a kind of fuse, whereby upon certain critical power load they will open saving the tweeter from injury. Thats why I was asking about its power handling capacity. I understand that if the power rating is too high, they won't do their job as fuses, right?

Yes it is strange that there is no reference to the MDN 0178 series on Caddock's website whatsoever, but it is clearly printed on the resistor itself. As far as replacement is concerned, I saw a new model on Caddock's website - the MPM 20 (with gold-plated leads). It looks like the best they have, but unfortunately it is not featured in any of the internet shops or Caddock dealers websites. Can you recommend where to buy them?
