As our Group Test that included those two models already stated, go with the Denon AVR-1909.
However, if you don't want to buy right now, there are new models coming through from other manufacturers, too. Not saying that Sony, Pioneer or Yamaha will be better, but they've certainly also been studying last year's storming Onkyos and are determined to improve on them.
All models at this price will be thoroughly put through their paces by our Awards issue - on sale October 16th.
