For all the 3808 owners, the new features are now available and the responses on AVS forum are all positive so far, other than having to re-run Audyssey and some configs needing to be setup again as the settings were lost. I have not done the new feature updates but have re-run Audyssey and have found it to be a marked improvement over anything I have heard from it in the past, much more open and natural sounding, IMO.
