I have a 6 foot set of Groneberg Quattro Reference speaker cables.
Purchased brand new from Klaus maybe a couple months ago.
Spades at amplifier end, bananas at speaker end.
Groneberg Quattro Reference: Patented design for optimized and constant electron flow • Four conductor lines • Stabilizing inner core • Shielding braid • Excellent soundstage, detail and deep bass reproduction • Harmonics coherent • delicate and revealing mids & highs • Excellent voice reproduction • 530 pF/m • Propietary jacket formulation.
Nice cables, but ended up not using them.
Just paid $375, sell $300 shipped including all fees.
