Hopefully this question is in the right section—I'll try to summarise quickly. I bought a new 2019 iMac. This was my previous set-up: 2015 iMac—headphone socket—optical/toslink—Yamaha DSP Z9 amp—B&W 705 speakers. It sounded great. Apple decided to stop digital output through the headphone socket in 2017. So, I have no sound if I try to use old set-up. Available outputs on my new iMac: headphone, 4x USB 3, 2x Thunderbolt 3 (USB-C), Gigabit Ethernet. What are my options to get the best sound possible? I presume reverting back to analogue and using a simple 3.5mm to 2-male RCA adapter cable would sound ok considering the amp and speakers? Thanks in advance for your help/suggestions.
