Default Why do people say they can't hear resistors, or all resistors are the same?

I tried about 7 different kinds of resistors of the same value on my tweeter it seemed damn obvious they all sounded and different - and what about the sound had changed. I even accidently used two different (nearly identical) resistors for each tweeter and heard the result as 'something wrong with the stereo field'.

Maybe its because I'm a recording engineer with more trained ears than the average joe I can hear them - but the sheer amount of people that say that resistors don't affect the sound is crazy!

So what is it? Just because they don't have have good hearing or what?

experimental setup, blinding protocol? statistical significance?

how did you get 2 (pairs?) of loudspeakers with drivers matched well enough? - did you use a Harmon style "shuffler" to put them in the exact same place in the room for each trial?

just because you're a recording engineer doesn't mean your uncontrolled subjective impressions have to be given much weight if you ignored all known steps for valid subjective testing

please explain how you conducted these "tests" and why your procedure is resistant to known psychoacoustic and perceptual testing errors
errors

haha whoops I guess I didn't think of how people might explode at that my bad i will maybe people shold just trust thier ears

edit: actually I don't really know how to do that - the mods can take care of it if they wan

Spice, we've had this kind of debate here many times, and it always ends up the same way. Unless you can offer objective proof that you're hearing differences, then it will just end up in a huge slagging match. Sorry.

speakers did not move - differences between them? much less than the differences between resistors, apparently. I'm not trying to do a perfectly scientific test with measurements (because speakers are for my EARS not my oscillator lol) but I'm not going to do something stupid like move them around to throw off my hearing.

the same pair or resistors tested multiple times sounded the same- because they were the same

there is a difference. I can hear it clearly. can't others? I mean it only makes sense that things that are different are different. not a troll thread - genuine curiosity

At least with resistors being used at high levels and low values, there's more plausibility. Thermal effects and inductance, for example. Not to say that these uncontrolled listening tests are valid (they aren't), but this is a far cry from stuff like crystals and kilobuck power cords.

I agree, mods please close this down.

Spice- whomever suggested to you that different resistors (quality, tolerance, brand, etc., etc.) don't make an audible difference, I'd suggest you do your venting directly to them. Is there a specific thread you can reference displaying a large part of diyers think resistor quality is mute?

And yes, so many are not graced with good hearing and the clout of being an audio engineer and thusly, are not audiophiles.

a recording engineer should be able to record the differences? - if the differences are there it is hard to imagine they can't be discerned in well done soundfield recordings

but digitizing driver terminal V would have fewer uncertainties

with data various hypothesis could be investigated but EEs do know a fair bit about component behavior and quite a few appropriate resistor type choices can be calculated to give extremely low magnitude response differences

simple frequency response differences from resistor tolerance can be considered "uninteresting"

thermal modulation of properly sized XO R might in principle be big enough to be seen in data - but insignificant compared to driver voice coil self heating

magnetic coupling perhaps?
