i've also received today the new nicehck cable, 7n occ copper, plated with pure silver and some gold color, 8 cores. it's also in the thick and heavy side (33.4g), but very soft and flexible, and conductivity is superb as well. 100,101,98,111 mΩ
sure you can get one of the cleanest sound with this cable, as with the 7n occ 4 cores cable.
this wire is also advertised in other shops as pure silver, but guess it's copper, with true pure silver plating.
7N OCC spc 0.05mm*48(27awg,OD:1.2mm)*8c UV-PVC sleeve [2c/signal: 24AWG]
the quality of the material and plugs (eidolic type, i like them more than furutech type, although bigger) must be very good, because i expected resistance to be about 120mΩ (10Ω higher), based on its structure and length.

some of the cables around:
edit: at last, i've given up about getting t88k. there is another good offer now, but the comments about their so thick sound (even thicker than audbos p4) make me feel they are not for me.
will wait for more reference and thinner iems.
