I have done several AES jobs. Work great. One job is actually a little over what they recommend for an Adagio system and it works flawlessly. Now, I wouldn't recommend doing that but in my case I had no choice. Actually have the AADS-XM installed in my house.
For your opening order, if you are going to be doing more Adagio go with that for your order. If not go with the newer MC3 for processor and the Sonnex stuff for audio. Maybe even check out the smaller DM switchers. Actually, they haven't released them yet.
