My system is pretty simple:
- iMac, Late 2012
- Yamaha RX-V367 Amplifier
- Jamo D570 Floorstanding Speakers (2 speakers)
I connected the iMac to the Yamaha with an Optical cable from the Audio-out of the Mac (using a Toslink adapter) to the Optical of the Yamaha. Therefore, I'm only outputting sound to the amp, no video.
My question is, do I need to upgrade to an HDMI cable in this setup? I know it would require me to purchase a Thunderbolt-to-HDMI adapter for the iMac, but I wonder if I am going to experience a better sound with the described system?
S/PDIF connections, both optical and coax, provide the same quality of signal as HDMI when playing two-channel PCM. When you upgrade to a surround-sound speaker system, though, the advantages of HDMI will become useful: eight channels of high resolution audio. S/PDIF is limited to transporting either 2 high resolution channels of PCM, or 5.1 of lossy Dolby or DTS.
