Acrolink Mexcel and Vitus Andromeda

I'm looking to upgrade my speaker cables and wonder if anyone has experiences with both the Acrolink Mexcel 7N-S9000 and the Vitus Andromeda cables?

These are similarly priced used, but I haven't been able to find much reviews of either of these cables. Currently using the Van Den Hul Revelation and just looking for an all-rounded upgrade. Grateful for any recommendations.
I am using the Acrolink S9000 and that is one fine sounding cable. It has a gorgeous tonal balance and very transparent. I compared it against the Acrolink S10000 & strongly prefer the S9000. The S9000 has a much more properly balanced and refined presentation and has waaaaay better bass and midrange.

S9000 is better than S10000?
How can it be possible and you think Acrolink is fooling us?
