klipsch cornwall iv upgraded crossovers

I suppose it depends on what one calls “subtle” and “obvious,” but if something has to survive YT treatment to constitute a meaningful improvement, I will agree that most modifications won’t pass the test.  It is up to each owner whether any improvement is worth the cost and effort.  It is not up to some self-appointed expert on cognitive dissonance to shame those who find such changes desirable.

@perkadin , wow, that's one mighty high horse you trot around on. Prove it to you? You've got to be kidding me. I've already proven it to myself. I have no interest in proving anything to you.

The OP asked for the experiences of people who tried these mods. I saw no mention of wanting the opinions of self-important, bloviating skeptics who have not tried the mods but are nonetheless convinced they do not work. No one is selling anyone anything here, so please back off with your suspicions and sophomoric psychologizing. Closed minds, closed ears. Good luck with that.

@wrm57 start with this Click here. You are fooling yourself if you think I’m the one being closed minded.  Ive done a ton of blind testing. I make a conscious effort to be as objective as possible when it comes to evaluating gear.  I don’t dismiss something as junk because it’s made in China or is less expensive or because some “expert” said so. I also consider behavioral explanations behind opinions. Do you?  

So, your comparisons of DACs on YT were scientifically controlled blind tests?  You were able to verify that the person making the video properly controlled all variables and your own evaluation was blind and you had enough samples to reach some level of confidence in the results?
 

I’ve participated in blind tests, including DACs, so I am confident that their are meaningful difference (though not at .05 confidence level), but, that does not mean everything outside of such testing is delusional.  It is unfair to insist on blind testing to prove modifications are efficacious, while insisting that YT videos should be provided by modifiers when there is no evidence (blind testing?) that YT videos can make differences, or lack thereof, evident.

@eoj4952 Check out my Video. Crites has the Xover Cap values online but never measured the Inductors. I changed everything and updated the Xover to include the Inductor Value. It's all in my Video,
