"mix and match" speaker cables.

Hi Guys,

Possible silly question here...my speakers allow me to tri-wire. Wondering if there could be any adverse effects (main concern to amps) if I were to...bi-wire tweeter and mid driver with brand A...and a separate run to the woofers with brand B. Nothing exotic....bi-wire cables would be Supra ply. MIT MH750 to the woofers. MITs are super old - 25 years.
As long as the cables are electrically correct, no harm could come from this...
