@lubachl Can anyone comment on their experience with Chinese "Odin" interconnect cables in comparison to those described above.
I have two sets of these connecting DAC to Pre and Pre to Amp. They replaced Belden 1800F (BJC). I cannot say I noticed a lot of difference in this case. My system is Gumby->Freya+ -or- Coda 07x -> Coda #8.
I admittedly have not yet tried a very high end interconnect, so I really do not know what is possible. That said, the ones I bought are very well constructed and appear to use quality components. They are a bit of a hassle to route as they are quite stiff, but once in place it is not an issue.
Sorry I can't give you a solid answer that they provide a big performance boost, but as always YMMV. It is a fairly low cost experiment, so not too painful if they do not work out.
