My streamer has digital output with specification "Digital output RCA 75 ohms: sample rates up to 192 kHz". To connect my DAC, I am using one of my RCA Cable - Luxman JPR-100, with specification "Conductor resistance: 26.4Ω/km or less (at 20°C)". Do I need to get any specific (matching) cable for optical output to get better quality of sound?
