Yes, a HD621 will work like this. Infact you can set the HD621 to downsample to 48k should your 2 channel system not handle 96k.

The only limitation is that the switching between inputs would have to be manual by the physical buttons on the HD621 unless you have a separate Meridian unit to receive and pass on IR commands via Meridian comms from a remote. (You could control by RS232 should that be of any use to you.)
