Speaker cables for Quad 57's

Speaker cables for Quad 57's? Quad II (original 15w/ch; KT66) tube and/or solid state, Classe DR-2 (25w/ch class A)
Look at Magnan Signature speaker cables..... They are enormously wide, individual cables - each one is 4" or so across, 2 to a side so beware of
visibility problems.....not for cats... The builder uses '57's himself.
