The new website looks great, and they have listed two new products, a 5 channel amp (classic) T-955 and a universal dvd player T-585. My hope is that they update the c542, but in a conversation with a NAD tech (who isn't really in the loop on these things) he said all he has heard about was an update of the 521bee to a 525bee.
There is a new pre/pro, too. although it is not up on the website, I got to see their press release announcing they will be showing it at CEDIA next week. I do not remember the model #, but I do remember it has four HDMI inputs and full up-conversion of all signals. It looks pretty awesome (as it should for a MSRP of $2K!).
