Would it be possible to interface digital cabling onto chassii with any benefit? I don’t know the voltages of RF travelling on chassii, they might not fit the standard of standard digital cabling, but maybe have a specialized RF cable that isn’t so much like the “speaker cable” they’re selling there.
