Why, according to Arcam, is HDMI bad for audio?
You need to look at the era for this unit. This is an HDMI 1.0 spec. So by comparison to what was capable over coax, yes this method via HDMI was far inferior to what you'd get with other digital connectors. it wasn't until HDMI 1.3 came out that there was enough bandwidth to offer the higher bit count modes. You must remember that the early spec was very locked down in it had to format the signal to a specific spec and even if it was just sending audio, a blank video package was also being encoded.
