Cheap ribbon cable vs UP-OCC with Teflon insulated is no contest.
What is the insulation of those cheap ribbon cable? I doubt it would be better than the Teflon on the UP-OCC. Not mentioning the plastic connectors which will degrade the sound. Direct point-to-point soldering most of the time will be better.
Worsen the SNR? I doubt such will be measurable, unless your insulation is outrageously bad or you are running several miles of length of wire.
I don't really want to argue, but for 'idiotphile' like me (YMMV), I put the top priority to remove this ribbon cable (also along with cheapo Green Alps). I don't want to remove the Green Alps as I only have 2 gangs DACT. I need to justify the impact to purchase 4 gangs DACT which the cost almost the same with a brand new E1.
The impact? I have used Green Alps on several cheap preamp project and after changing them with DACT or similar stepped attenuator, the different is night and day. This is no brainer answer.
Other plan is to re-wire from the 'ribbon cable' to take 2 channel only as I only use the unbalance out, directly to the 2 gangs attenuator (DACT) and let the other 2 channel for the balance use the original Green Alps. I havent traced in detail but have gotten some of the tracing result on hand, but I think that is very possible to be implemented.
Low inductance doesn't mean good sound (this is 'idiotphile' practice - off course people with degree in Engineering will ROFL reading this). But it's a matter or personal taste and preference, right?
I use mostly Ceramic if your intention is for high frequency decoupling. They are also very cheap and widely available.
See my other DAC project with Sprague Multi Layer Ceramic below. They are one of the best for the purpose (YMMV).
Kudos to ASUS for such great DAC, and with this mod, I believe it can compete into a higher level (at least now I can enjoy more than before). Sorry if this mod is not for everyone.
Again YMMV, thanks for sharing.
