2 Channel & Home Theater

Hello:

I just acquired a McIntosh C55 and MC257.  I, also, have a Marantz 7703 pre and 8077 amp.  I would like to use the McIntosh for 2 channel music and Marantz for HT.  My speakers are B&W 703 S3, HTM71 S3, JLAudio f10 and B&W 705 S3 signatures.  

I have my Innuos ZENmini mk3 and Denon DP-62L connected to the McIntosh for music listening.  

What would be the best way to connect the components so I can switch between 2 channel music listening or HT.

Thank you for any help you can offer.
