Hi. I believe that the Yamahas about that price range offer this facility - though I think you may lose the multi-zone facility if you have bi-amping set to on.
BTW your long subject heading causes a problem when replying.
Mind suggesting a few AV amps you speak of?
Onkyo 609, you can grab that around £400, maybe cheaper.
Panasonic 65" 3D TV (P65VT50), Pioneer LX83, CA, Azur 751BD, PS3, Water Cooled Xbox 360 (Modded), Nintendo Wii U, Sky HD+, i7 PC overclocked with 6850 HD Radeon, CM8 Fronts (Bi-Amped), CMC Center (Bi-Wired), DS3 Dipoles, PV1 Sub. Van Den Hul M.C. Snowtrack >Halogen Free< wiring, Chord Active Silver HDMI's, Cabridge Audio AUD700 Analogues Interconnects, QED Signature Subwoofer cables, Chunky Monkey custom oak AV cabinet.
RX-V671, 771 I believe.
An old Arcam AVR250 or 350 - these can be had for about £250 and £350 these days (funnily enough).
I bi-amped my front speakers using my AVR250 for a while - thinking about doing it again...

That Cable HDMI, Chord Crimsons and Sonos ZPS5s everywhere & a spare Yamaha RXV-667!
I believe the Pioneer VSX-922-K can bi-amp.
Why would you want to? none of these amps will act as an active crossover so in reality you gain nothing.
On the contrary, you can gain something. If you have a (probably physically small) extra pair of speakers, you can connect them to the amplifier using the Bi-amp speaker terminals, as well as connecting a normal pair of main front left and front right speakers. The extra pair of speakers can then be positioned about seven to eight feet high, above and slightly outside the main front left and right speakers.This is what I have done in my kitchen, and the sound is definitely bigger and better than without the small pair of Yamaha NX-E130 speakers connected to the Bi-amp terminals. (Though I must confess that I have no experience of using main front speakers that have Bi-amp terminals connected in the Bi-amp configuration to the amplifier, and then of course not using a small extra pair of speakers.)

More power means less strain on the amps. Important for metal

But passive bi-amping doesn't gain you any power. If you could bridge them then that would be a different story.
