The only way you can determine whether a, "better" cable might make a difference, when it comes to YOUR listening pleasure: AUDITION a few. Their are a multitude of variables and no one can answer the question for you.
Ideally: that would take place with the intended gear, but: since Mogami's variants are preferred by the manufacturer of your target amps, you might begin by comparing other cables with one of theirs.
To me: the least painful way is renting test subjects from The Cable Company*.
ie: a pair of Kimber Hero or Silverstreak variants, in XLR, would cost under $100 to audition/compare, in your home, with your system and ears.
