Nordost Blue Heaven to Analysis Plus Crystal Oval8

Will this be an improvement? Currently using the Blue Heaven speaker cables from my Plinius SA-100MkIII to the Sonus Faber Grand Pianos. Have searched the archives and read good things about the Oval 8's. The Blue Heavens are good cables but I'm just wondering whether I would get even better performance with the Analysis Plus wires.

Any inputs will be appreciated.
