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.

Hello I have experimented with Vishay,Caddock,
For Loudspeaker networks the Duelund was the best IMO at dissapating heat,and a Very neutral and natural presentation .
Recently I heard from friends across the pond in the U.K about the newest
Best resistor ,also incorporating a ground off the Copper chassis.
A company called Path Audio,hand made in Poland. They are a bit pricy
But the most natural resistors I have ever used.this includes others that have many years in the field. These resistors do take a solid 100 hours
Before fully settled in. Well worth the expense,$35 retail and at a 1% tolerance The best in the business for a Loudspeaker Xover.
I agree with you with the Cast resistors they are excellent. Email Hifi collective in the UK. 100 hrs min for runin and recommend using the ground to the Loudspeaker terminal as a RF screen.
The Path Audio resistors and Duelund resistors are both excellent
The both sound different in a given circuit. Duelund tolerance are 5% and
Path Audio a1% which will be a bit better in driver accuracy to a very
Small point.
this is from Path Audio ,and I confirmed this from other dealers in Europe send from Path engineer below.
Yes, Duelund resistors are good. In my opinion and our customers, PathAudio resistors have some advantages:
- dynamics
- smoothness
- more „body”
- better micro details
- much better resolution in high frequencies
- much better bass when it’s parallel (with capacitor) to woofer
- neutral in midrange

If you have find it better in 5 hours… then there are a lot of new experiences to go :)
You hear probably also the new soldering now. I think 2 weeks from the begining will give you about 75% of the overall performance. The total smoothness will appear in about 1-2 months, depending on the intensity of playing hours.
If using the larger Ohmite Gold,or Mundorf Supreme larger resistors with soldered legs ,Cut them off just above the riveted  legg. reason being the legs are dipped in Nickle, a horrible addition.i take awg18  Neotec Copper Wire 2inch ,flux and solder good 4-5% Silver content. Sounds noticeably cleaner after 24 hours or so of play 
Path Audio resistors are the best Period just Hook them up .
myself and others checked tolerances on over 8 pair less then 3/4% of 1% on average min-max ,by far the best.Teir  engineer said give them 200 hours to fully open up- refine.
For small under 1watt the Vishay naked, are the most detail refined 
resistors.  ThePath Audio resistors in the 10 Watt range are top dog a slightly warm balance detail the best out there . Myself and others have measured them on average under 3/4 of 1% .nothing 
cones close Duelund 5,and 10% add in a few % 8-13% . On average $28 each. The 1% ohmite Gold, and big 20watt Mundorf Supreme are very good Butthey gav3 soldered leggs cut them off as I did and replace withNeotech awg20 6-9 solid Copper poly r Teflon jacket high percent 4-5% Silver solder much better sounding for the soldered leggs are Nickel plated ,how stupid !!
I have to say several tell me go with dpeciak brown ohmite ,carbon or micacomposit.
Even the Duelund Cast adds a bit of sonic signature. WILSON USE or did use caddock very neutral but lack a bit of nsturalness and depth . The path audio 
Given the proper Loong 150 hour+  was told to me by the engineers as well as owned for max detail and soundstage width,depth.  J documented and they were correct. The attached ground wire going to ground in crossover can make a difference ,all my capaciyors were measured and or outer foil documented 
With cactus symbol ,or line in Jupiter Copper foil.
Other caps must be tested on a scope,or noise meter. And without question 
Optimizes detail and super low noise floor. The Path resistors just complete 
The build, natural musicality end result.
Pathaudio the best balance but over $27 each
the Mills mt12 I never have foundthem lean sounding after 75 hours 
with these Ar perry non. Inductive windings and special ceramic mix take time settling in .ido like the the fact silverplatedcaps, and leads Tinned Copper.sonicly 
mundorf Supreme mresist use nickel over copper then rivet leads, a bit harsh
i had to cut off and resolder with Neotech wire  much better balanced sound.
for the buck Millls mr12  a much trustedresistor at $4  ,if you  can’t afford the 
path Audio ,and don’t want to modify the legs on the big Mundorfs $16 each
same goes for the ohmlite gold with the rivets  very good but get rid ofthe rivets.
to get the most out of them.
For. Loudspeaker Xovers hands down the Path Audio resistors 
very musical and natural and super low distortion out of a 10 piece sample notone was more then .75 of 1% which is incredibly accurate I have been using these for several years now the best I have ever heard and I have heard everything in North America ,$25 a pop isexpensive but these are well worth it. Since parts connecxion never has ample stock,I just order from Hifi collective in the UK fedex int priority under $30 and usually delivered within 2 daysis fantastic.
