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.

Great,

looks like i should just ditch the duelunds.

I have always had the problem as you described thin airy and bright (adds details).

I never got a tighter solid center vocal imaging, it always sounds larger than life with the cast resistors, goes with the airy wider soundstage.

i was just thinking of changing the resistor to the midrange as i felt is has a upper midrange brightness that was a bit painful on brighter recordings.

I do however, like the overall presentation so far, guess from you description, it is worth a try (just hope its not too much of a direction change to the sound). FWIW, i am using a cast cap for the tweeter as well.

It's just quite startling just 1 resistor can contribute to the sound.

SalectricOne more question.

did you use the same value.

I am getting some tinnitus form the highs currently s i did not mention as i like rock on a louder volume :)

I am asking as i feel that there may be seem to be a boost in the highs, could it be the bright and thinny highs.

I shall post my impressions, sadly they have a lead time as non stocked of a couple of weeks, darn!

I have PathAudio resistors in 2 spots which are 5 and 10 ohms. Right now I am still using Mills in the other two positions. I plan to get some more PathAudios to try there as well.

You may want to break in the resistors before you put them in your speakers. I hook up new parts to the speakers in my video system first so I can run them 24/7 for a week or so without messing up the sound of the hifi.

Thanks Salectric,

I have just got my resistors in, 1 for the mid and 1 for the highs.

Just deciding if i should do 1 at a time or dive in with both.

The resistors you have are all in the high network? Just curious why you still have a mix of duelunds and mills.

Did you find a mix better than all pathaudios?

Yes, my resistors are all in the high-pass section of my 2-way crossover. And I am using a mix of Mills wirewound (black body) and PathAudio. I am not using any Duelund resistors these days.

As for why I have a mix rather than all PathAudio, my speakers need some emphasis in the extreme highs, and the Mills provide a sparkle or shimmer that the more neutral PathAudio does not. It is not a case of one being better than the other. You have to mix-and-match to get the particular sound that you were seeking.
