Bi-amping Harman Kardon 7.1 models?

[altair4]

Read on this review site that a guy had bi-amped his H/K 7200(american model).

H/K 7200

Im wondering if you think its possible to bi-amp H/K amplifiers in a similar way as denon 3805? Im getting the AVR 630(european version) and it would be great if I could use the two extra surround channels to bi-amp my fronts since im not gonna use em anyway.

Has anyone tried bi-amping H/K?

Can you select the same source for both zones?

I don't think passive bi amping is worth the effort anyway. If you're clipping now, you'll still be clipping after passive bi amping with the same size amps since the channels are still driving the full frequency response.

I would make more sense to get a bigger amp if you're running out of headroom. Does your receiver have pre-outs?
