Axiom Home Page Forums General Discussion Home Theater Yamaha's low-end offerings?

Hi all,
I was checking out one of the latest (I think) offerings in the HTR line, the 5840, but didn't get the chance to audition it, and one feature I thought would be great is Silent Cinema (surround sound in your headphones), and also the quadfield DSP, which is supposed to give you surround sound without rears. Anyone heard what these sound like, and are they worth while? Jorge, what exactly about the H/K is it that "blows away" the Yammy? (I realize HK is in a different class, but just wondered!).
Cheers!
