As it’s been explained to me by one manufacturer of balanced amps and preamps, Since many balanced lines are driven at 600 ohms (like pro gear) I believe, that in itself takes the cable type more out of the equation compared to unbalanced.
The IC cables I’m using in my system are (cough) uber cheap mogami gold mic cables (which is their top end), since I’m using close to a 15 foot run to the BHK 300’s.
When the 300’s arrived I needed basic cables to get them running, and I never replaced them in the almost 2 years I’ve had them.
In a truly high end cable that length would be astronomical cost wise. In the 3 foot run from the DS to my balanced all tube pre amp, I’ve auditioned uber expensive cables and often the difference was subtle. Could it be that the run of mogami gold from pre to power was masking the difference? Possibly, but I’m more focused on trying to find the ideal speaker cable, since even some manufacturers have said that the speaker cable reveals more differences because of the higher current.
I’d love to try Teo liquid speaker cables - but they are quite expensive and I’m currently doing quad wire with my current set up.
Perhaps that will change with PS’s new speaker. Till then I’m making no investment in cables.
