Reply to American Audio Radius 1000 vs Radius 2000

Right well I have a dilemma here thats seriously pissing me off.
The American Audio website is terrible and there aren't many reliable reviews of the Radius 2000.
Thomann.de lists the Radius 1000 as roughly $50 more than the 2000 model. Although both seem to have the exact same features and usually a model called "2000" would be more expensive than a "1000".

Is there anyone who has owned any these - particularly the 2000 - who can give some sound advice as to which model to choose?
