Hi,
I am not an expert but can tell you that I went all in with DH Labs cables and my system felt bright, a bit tinny and lacking in depth. Then I tried just one Snake River Audio cable (the Boomslang SPDIF). I was literally blown away. Since then I have been slowly replacing all my cables with SRA. Surprisingly, changing the ethernet cables to SRA also had a huge positive effect.
The SRA power cables bring a sense of depth and calm to music. It is not like they add anything, rather they strip away sterility.
Oh, and I have the Focal Sopra 2s...
