Main reason is I'm thinking of getting the 1001RB for the bi-amp feature and more headroom.How come you're looking to flip so soon; not your cup of tea? The short answer is no, I'd say it wouldn't be worth more because of its rarity, unless you find somebody that's a GK collector and absolutely needs one to complete their collection. There are IMO two reasons why those 1000RBs are so rare, and they're related...
