The question I have. Would you recommend to:

- Keep the two separate, enjoy movies with the JVC and music with the HK and the B&W?
- Connect all speakers to the Harman Kardon, using the tall B&W left and right speakers instead of the L&R of the JVC?
- Connect all speakers to the JVC home theater system, using the tall B&W left and right speakers instead of the L&R of the JVC?

Bear with me for the basic question as I am not an expert.
Thank you for your support.
