I don't know what it sounded like with version 1.0.1 because I sent it back to the Outlaws for the upgrade before I hooked it up. Getting the upgraded firmware free and easy with Outlaw was a no brainer for me especially since I have heard all kinds of issues with doing it yourself. Onkyo would not release the ability for the DIYer to do it at home. The forums over at AVS hint that there are fixes for a few small things and allowance for using different remotes codes.
