I doubt it’s any better or at least better that’s worth the money.
But if you need a different longer length (11m) then that’s another question.
There is no specifications shown in Mark Grant website, the important spec is inductance, Naim amps require a minimum 3.5uH per channel.
So find out what the MG Van Damme cables inductance is.
Looking at the spaced conductors I suspect it’s around 0.8 to 1uH/m, so so 11m will be around 10uH and OK for your amp.
