Digital Coax 1.5m

[markush]

When I got my Devialets as monoblocks in 2016, I went COAX-to-COAX. But soon, realised that COAX-to-XLR sounded much superior.

Hence, I had Audioquest Diamond as my cable and 1.5m length. I was upgraded by Audioquest to their WILD and the improvement was very substantial. Finally, I went with their Flagship WEL Signature and it is a helluva fantastic cable.

Haha nice - I am also using the AQ WEL Signature for connecting the monos.
This provides exceptional performance, and there is no difference when using the iFi SPDIF iPurifier2 (even power with a battery for 100% isolation).
But if you use cheaper cables, the iFi is really a good option.
