What do I need?

Since ours has to exist in the same space, one just has to adapt ones' mains to handle both with aplomb....make judicious selections of how and what to connect, and it can (and does) work....

This topic discussed many times before. The best way is to separate home theater system from the audio system, so optimal way would be to have home theater receiver connect to own speakers. 

"Optimal" as noted would be 'bare bones' in the audio segment 'round here, 
@surfmuz ...  and since the AV/HT is also covered by the necessary components to potentially overdo the end product...

And agreed, the field has been plowed to bedrock many X times, so...

Success on both fronts asks for a subtle approach as to the marriage of same, in spaces that can uncooperative in too many ways....

Been doing AV/HT before the HT name went 'household necessity' to the masses; so have been there too many times; managed to save some sort of sanity....even if some will disagree with that.... ;)

Play loud and often, J

Look into Anthem Audio.

For what it’s worth, I read each response a couple times over a day or two & compare it to the others. I really do appreciate all the responses. I really do. I usually wait till the next great slows down & thank everyone. I see other people do this all the time. So, pick yourself up by your pamper straps & don’t be so sensitive.
