I integrated my 2-ch system into my home theater, without a theater bypass option on my preamp. While this feature is useful, it is not required. I simply run the left/right main outputs of my AVR (obviously, this requires line-outs for at least the main left/right channels, your system link does not list which surround receiver you have) into an input on my stereo preamp. The stereo preamp feeds an amplifier for the front main speakers, while the AVR powers the rest of the speakers in the system. Having full range speakers up front is preferable in this setup scheme. Setting the stereo preamp to a repeatable volume setting (I have a digital readout, so I use "60") I then balance the surround channels. Any time I want to listen to a surround source, I just set the stereo preamp to "60", and use the AVR's volume control to adjust the volume for the whole system. When I want to listen in stereo, I just select a different input on the stereo preamp, and shut down all the surround gear. For video, I run HDMI from my universal player into the AVR, and the digital stereo output to a DAC, which in turn feeds an input on the stereo preamp. No need to hook up multiple amps to my speakers, which is indeed dangerous. BTW, the second set of binding posts are not for hooking up a second amp with a different signal, they are for bi-amping or bi-wiring the speakers, which is something completely different.
