What do I need?

"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.

Sorry OP, I disagree, feedback essential so that we know that we aren’t wasting our time trying to help you.  You still haven’t answered “does your preamp have a HT pass through?”.

In laymans terms for a surround system you’ll need something to split the signal into channels (preamp-processor), provide amplification to each channel, followed by a speaker per channel.  A HT (home theatre) pass through on a 2-channel preamp allows use of your 2-channel speakers in your surround setup.

If your 2-channel preamp does NOT have a HT bypass feature, I suspect your only option is to directly wire your 2-channel speakers like the rest of the surround speakers from your surround-preamp-processor.  

So, pick yourself up by your pamper straps & don’t be so sensitive.

seriously?

You respond after 6 days, you claim you respond on day 2 and you have this attitude? Wow...
