btw, i've updated the info about cable 194, after getting more info about its composition.
very special wire, from the US, not up-occ. it does contain 7N single crystal copper copper, like i figured after noticing the bass extension and rumble, and pure 5N sterling silver. wide extension also at highs due to flat silver ribbon. very interesting.
194. eac 5n ag & 7n occ cu frz 2x2c (silver,eagle,MV): 218..220..99..109 mΩ..[25.1g]..170..166 pF..[120cm]
core OD: 1.65mm. outer diameter: 4mm. length from splitter: 40cm.
5n sterling silver ribbon (65%), 7n occ copper, "double-layer freezing treatment", from the US.
electro acousti shop.
don't know its structure, but it looks like there is an inner conductor, some kind of insulation, and then a layer of braided ribbon (flat wire) of pure silver. so 2 conductors inside each core.
don't know the sleeve material, but guess it's PVC or even teflon, because the wire is stiff and springy, harder than PE sheath.
this topology is different to any other wire i've seen, and the sound you get when using it is also unique. very interesting.
resistance is amazing, very low, for such thickness (specially the ground/negative conductors).
inner conductor is used for one signal, and the braid silver layer for the other.
i was expecting that highs perception would be improved by using flat silver wire. and they are indeed, but the rumble of lows is also remarkable, unexpected from this frozen silver wire (maybe round copper inside?).
edit: yes, description update confirmed it uses copper as well, which explains the bass rumble.
so extension is huge at both sides.
soundstage is wide, and bigger overall than any other cables, but up-occ. same for background noise.
very good sound overall. i have to listen and do more AB to further compare it with up-occ wires.
