integrating H-T and 2 channel systems

How best to connect a 2 channel sound system and H-T using common front L-R speakers? I plan an AVR central to surround but using a Benchmark DAC-Pre  with monoblocks for 2- channel.
Can I "biwire" the front L-R speakers with connections from the receiver  and each monoblock to the single terminal of each speaker?
(H-T and stereo never to be used simultaneously)

You should not connect the AVR and the monoblocks to the speakers simultaneously.
Does your AVR have line-level outputs? If so, you can run the left and right line-level outputs from the AVR to the Benchmark's analog input. I presume that the Benchmark doesn't have a unity-gain bypass setting, so you'll need to mark a place on the volume control that is repeatable. Set the Benchmark's volume to this repeatable setting when you calibrate the individual channel levels, and return to this volume setting whenever listening in surround. This technique has the added advantage of using your monoblocks to drive the left and right speakers in surround mode, which also puts less stress on the AVR's amplifiers.
