I am not bothered by the inability to upgrade. There are a few products that offer it but many more that don't. By the time I am buying something that has the next latest and greatest features (a few years off to be sure) I will want the newest DACS and latest input standards to be met. Unless you get one of the couple boxes out there that can take daughter board upgrades you will need to upgrade regardless. I like the way mine sounds and the ability to upgrade wasn't on my list of must have's for 899. I figure that if I can sell it for a portion of what I paid for it when I upgrade I will be doing ok.
