Shsu is correct, the 6600 replaces the 6900. I was able to hear the 7000 this weekend at a show, AKFEST, in Livonia, MI, unfortunately I very much disliked the speakers it was connected to. Aball (Authur) has posted some comments about it on these forums, do a search.
While I would find it interesting to hear this intgrated, in a better setup than I did this past weekend, I find it a shame Mac didn't use the digital volume and readout on the 7000 as they do on other gear, including the 6600.
