    The one stance I take, and always will: a mic will never replace the summation of sound our brains do which generate our preception. That is why even the uber-glaken mic that can measure to impossible-hertz with giga-K resoultion is STILL nothing but a tool.

    From there is it up to a human to use their ears, make coorilations to the data, and figure out what works for them... Which is not always what the "guru's" say.

    If it all was as easy as trusting a mic 100%, there would be no need for the diversity in this hobby.

    It's art built on the foundation of science! :eek:
    It's art/magic when you don't know how it works. It's science when you do. :D
    In fairness there is one application where the ear/brain is superior to even the best testing gear, and that's the ability to separate the acoustical wheat from the chaff, or to be scientific, direct from reflected sound. That's why a bootleg tape made at a concert is hardly ever intelligible, while concert goers hear everything just fine. But when it comes to any kind of measurements the ear/brain has less accuracy than an RTA with one octave smoothing.

      Wow! In all my years as an oddiophile, I've never heard any of my countless capacitors click. I've never even heard of such a phenomenon until now and I've spoken to some wildly off beat, passionate/superstitious personas in this game.

      This is a most curious, seeing Jesus in my toast like development and one I'll not likely soon forget. Should I be sad, amused or just confused? I know which one it is now, but what do we do to move forward? There's just no coming back from times like this.

      Shine on!

        Sorry, but I just can't leave this alone. IMO, it's more than just "measuring" response. The right crossover (therefore, the right caps) can improve imaging, soundstage, depth, transparency....things that are lost in translation when strictly "measuring response." JMHO. I would not say this if I had not experienced it. Even if you had THIS, it's not going to "hear" the music like your ears and perceive it like your noodle.

          I know. BORING...

              Hopefully I will get rolling on this by Saturday
              • Have all the crossover components.
              • The XO is very simple (gonna scrap the OEM bypass, although I do have some different ones to test just for fun).
              • The guinea pigs are a set of Polk Monitor-40's which are identical to THESE GUYS and one hell of a bargain at right around $100 on ebay from POLK DIRECT. My Jantzens have been in these for 3 months.


              All I need to do now is get my lazy A$$ in gear.

                  Do you have a meter to measure the capacitance of your caps?

                    I have built several sets of speakers, but my favorite project is fiddling with crossover rebuilds. It might surprise you how much better a $100 set of vintage used or even new mass-produced speakers sound with better internals.
                    Find a candidate with a solid build and good drivers. Rip out those factory NPE's and replace with something good, maybe swap out the iron core inductors for some air-coils, yeah buddy!. That's some good audio there ;)

                    I've never used Solens. I might just try some to see If I hear the click.

                    I have read about using a wall wart wired up to caps as a "cap cooker" but I've never tried it. I guess something like 5-9v would be safe. Get two identical caps "cook" one, compare 'em, solve the mystery.

                        No. I only have a crappy digital multimeter from Rat Shack. For the purposes of my test, why do I need to measure my caps before I build the crossovers?

                          I have read that article and the one by Tony Gee @ HHH. They are both excellent reads, and I really value their insight.

                          I have not seen a documented test similar to what I want to do, however, so I'm still going to give it a go and see what happens. Some of the caps in the above mentioned articles are simply cost-prohibitive to most people. I'm no audiophile, so take whatever conclusions I arrive at FWIW.

                            Here’s a set of music I plan to use during the burn-in phase of the capacitors. It’s just under 1:20, so it will fit on a standard CD if anyone wants to download. It’s one long MP3 track (320kbps) with the music seamlessly blended. It’s multiple genre – Jazz, Classical, New Age, Easy Listening, Rock, and Alternative. I tried to pick a set of rather complex and dynamic material. It’s for testing/burn-in purposes only.

                            Here’s a set of sounds, repeating frequency sweeps (all 20Hz-20kHz), pink and white noise and a complex combination of music + noise meshed in with periods of silence. Most of the material was obtained at http://www.burninwave.com/ -- Again, the program is one continuous track, this time in *.WAV format. It’s 20min long.

                            I will be looping both of these together for several days when I actually burn in the caps.

                              Because caps can vary in value from their specs. The naysayers will say this variance is what you hear and not any differences in the caps themselves.

                                Just to let you know...

                                ...you're in for it, bud!




                                Even though I did my homework, and really designed everything pretty much from scratch, there were still nay-sayers and believers. Some now believe they can hear a difference, whether scientifically/engineeringly proven or not. Some stated they had not a clue, and others thought they heard a change- and thought wrong.

                                Also be advised- it takes varying break-in periods for caps to 'click', so every circumstance is indeed different.
