thanks for the writeup Simon. I have no experience with it but I would consider making the upgrade. One thought for HDMI sync issues- check out the "Gefen toolbox" HDMI splitter- I need to generate 2 HDMI signals out of my Kaleidescape player and this does the trick- its really excellent.

Best regards,
Jerry
