Well done, I am very pleased you are enjoying your system so much. As for HDMI, Meridian won't have it in processors for audio quality reasons. It introduces too much noise hence the reason to build the HD621 in the first instance.
Well done Martins Hi Fi too, it's good to hear about great service.
