The stock Hifiman cables that came with the Ananda and HE6SE V2 sound fine, they don't get in the way - a bit short - and I have 3 different cables from Hifiman - the 2x 3.5mm to 6.35mm (fixed), 2x3.5mm to 3.5mm+6.35mm adapter, 2x3.5mm to 4-pin. For my use I am using the 3.5mm/4-pin cables mostly, and ordered new cables to see if they are a sound / fit / physical improvement.
These GUcraftsman 8/16 core Silver/Copper cables have a good reputation, sell on AliExpress and Hifigo.com and ?. Shipping Monday, and shipments usually take 3-10 days from Hifigo during the Covid-19 affected shipping over the last year, typically from my experience AliExpress takes weeks longer, I'm in CA, USA:
FYI - I'm only interested in balanced cables, prefer 4mm connector, and the 4mm termination option is what I've ordered here:

GUcraftsman also has one 16 core cable, but only makes it for HD6-- series headphones, and only GUcraftsman's Aliexpress store has it, I'll ask Hifigo if they can source it / list it before I order again next month:

Next month I'll try the 16 core cable and ask for GUcraftsman if they will build a Hifiman 16 core cable. Wonder if I can get them to make a mixed Silver/Copper 16 core...
