The good news is that I can get a box to convert HDMI to 4 times SPDIF (so the full 7.1). This would be the way to connect HD-DVD, Bluray and the latest generation of consoles (Xbox360 elite and PS3) digitally to either your G68, 861 or DSP speakers.
However, there's a big catch ... I need to order 100 units, since they have to be built custom. I still hope to get a quote for less units, but don't think this will happen. So the question: how many Meridian users would be interested in this?
