I have the Sherwood and was considering sending it in to get the SNAP but I am going to wait and see if they work out the kinks.

After reading numerous posts on AVS and other forums people seem to say that they notice little difference and that it still tends to set their speaker sizes incorrectly in the auto set up which has been an ongoing problem with these units, mine included. Generally this is not a big deal because the speaker sizes can be adjusted manually but, evidently, if you set them back you lose the SNAP settings. I don't know if they have ironed this out yet but I have not heard any new news. It is still an amazing unit and I plan on keeping mine for many moons.
