Thanks to both Nic(k)s!

OK, that's an interesting option- so to get this straight in my head, if I had a 'universal' BD/DVD/CD (SACD??) player (e.g. an Oppo BDP95, etc?) which could output through HDMI, then the HD621 would decode and route appropriate audio to the 5Ks and Screen for BD/DVD, and apodize 2-ch CD to feed out to the 5Ks?

Cheers,

James
