    DIY Ground Box Thread

    definitely something i thought about too, tho i think with a fairly good distributed mix the chance of getting wildy varying results is fairly low i imagine you can settle things quite easy with lifting the whole ground box and let it "fall" 1-2cm to the ground a few times :) .... tapping...

    DIY Ground Box Thread

    not sure how this works on powder but usually its just a small oxidation layer "conserving" the silver under it yea i think my test with different conducting materials is also unclear ... "i think" there are some correlations, for example the pyrite you can use quite much of but for example...

    Hello, i was playing around the other day with these materials around piezoelectric crystals: (1Oz) silver copper 1-2mm elite shungit pyrite magnetite i would say i found these most interesting: silver - honestly a bit subtle but still a very nice effect, it seems to boost "neutrality" with a...

    i just grabbed a 2 euro tester from aliexpress a few days ago to test around myself here, i think the supra tester works with the same principles, tho maybe with less or more sensitivity https://de.aliexpress.com/item/1005006338698828.html proper shielding does the main job of reducing stray...

    ok the ion tester arrived and i had a little play with it... first, it shows 10 * 10 * 10 * 10 ions per cm2, so if the tester shows "1" it means 10.000 ions per cm2 i kinda found out that if you move it around that it actually seems to be more precise, best example is if i hold this thing in...

    ah thanks, i wasnt aware of this, specially interesting since i think there is a correlation between placing conducting materials near piezoelectric crystals (lower resistance = better) just bought a 1Oz silver coin to test this theory further, and i feel stupid not have started investing in...

    260 kelvin is -13 degree celcius, so i guess above -13 degrees hematite (alpha Fe2O3) is weakly magnetic

    good question... i thought no but i found this: ----- Fe2O3 can be obtained in various polymorphs. In the primary polymorph, α, iron adopts octahedral coordination geometry. That is, each Fe center is bound to six oxygen ligands. In the γ polymorph, some of the Fe sit on tetrahedral sites...

    no problem, i think you can test with a magnet if there is magnetite in it ----- i also bought some hematite "rings" from aliexpress to see how it stacks up to magnetite (mainly to check magnetic vs non magnetic of "similar" stuff) "Hematite (/ˈhiːməˌtaɪt, ˈhɛmə-/), also spelled as haematite...

    this doesnt seem to be magnetite (but maybe also worth a shot) " Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe2O3. " "Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe2+Fe3+2O4 " (short formular is Fe3O4)

    https://de.aliexpress.com/item/1005005909996282.html there are cheaper options, this was the offer i bought for 34 euro i also bought this one: https://de.aliexpress.com/item/1005005450752171.html but keep in mind that all electrical negative ion generators also produce ozone as a...

    well once the negative ion tester arrives i let picture speak, of course i try to do it methodical i will first try crystals on top of speakers.... same amount of crystals +/- 1g, same crystal size (i got mostly 1-3mm stuff but also some powder stuff to compare), different crystals probably...

    this is graphite, not magnetite couldnt find much offers on the EU market and it somewhat lines up with the EU prices i just bought 100g powder for 9 euro from a EU seller rough magnetite crystlas 5-10mm is also around 10 euro for 100g 2-5mm 10 euro per 50g What does this stuff cost in US? im...

    Is this normal behaviour for dacs?

    the -78.7db are also SNR, maybe this gets calculated into the thd+noise measurement? Here with distortion lowpass at 20khz gain -10db: -92db noise is probably more in line with what amir measured it makes sense that SNR goes down with reducing volume... i guess the thd+n measurement takes the...

    Is this normal behaviour for dacs?

    Can i take from this that noise is "always" higher than any distortion component? and distortion just shows up because of the FFT processing?
