My special cable measured -92db with nothing changed other than the cables.
Sounds like you discovered something very important. What cables, wire and plugs are you using? Not everyone makes their own cables, it costs just as much or more to make an excellent cable and not very many people have the equipment or knowledge to test it.
I like Zenwave but buying the Furutech FP-108(R) UPOCC copper center pin, rhodium plating; Neotech 26 gauge UPOCC silver/gold alloy with teflon insulation; and Neotech 24 gauge UPOCC copper with teflon insulation costs as much as buying one.
Kimber Kable has crosstalk measurements (which I don't understand, 92kHz is higher than I can hear), what you have achieved compared to their measurements is amazing. Do you also measure capacitance, series inductance, dc loop resistance and reactance?
GQ - Mini Cu: Crosstalk @ -60dB - 92kHz
(Cp) parallel capacitance: 61.0 pF @ 20 kHz
(Ls) series inductance: 0.84 μH @ 20 kHz
(Rdc) dc loop resistance: 0.089 ohm
(Xt) total reactance: 0.104 ohm @ 20 kHz
Frequency response ±0.5 dB dc - 5Mhz
TAK Cu phono interconnect: Crosstalk @ -60dB - 92.0 kHz
(Cp) parallel capacitance: 47.10 pF @ 20 kHz
(Ls) series inductance: 1.31 μH @ 20 kHz
(Rdc) dc loop resistance: 0.119 ohm
Ground/Shield: R: 0.065 ohm X: 0.359
(Xt) total reactance: 0.162 ohm @ 20 kHz
Frequency response ±0.5 dB dc @ 5 MHz
Looking forward to hearing more about your cables.
