I'm relatively new to using an aftermarket cable for anything more than aesthetics. I just recently picked up a couple, balanced (2.5mm), 4 core, 5N/7N silver/copper cables and they've made some incremental improvements, to some of my collection.
I see for the pending 11.11 sale, KB Ear is discounting their 2 Core UPOCC Single crystal Copper cable to $40 USD.
I've got a rudimentary question:
can a 2 core really be a balanced connection, as you end up with a single core for each side ?
To elaborate, if this image represents a multi strand, single core:
There wouldn't appear to be any isolation between the strands, for the L/R signal, for each, individual, earpiece.
