Any Consultation available to set up a system with used equipment

it sounds like you are in a dangerous situation where you may end up spending a lot of money for little value. I would decide if home theater or 2 channel were my priority and focus on one. 

I doubt you'll find many audiophiles or enthusiasts consider it a dangerous situation situation or spending some money for little value otherwise we'd all just have a transistor radio.

Thanks everyone for ideas , basically my set up now  which is used equipment from my carpenter friend years ago …..804 s and center b and w speakers a 400 watt emotive 2 channel amp with a 200 watt rotel amp for center channel and 100 watt rotel for back speakers I believe energy bookshelf…..oppo 105D for blue ray and marantz 7006 receiver that runs through oppo DAC …and old 1080 Sony 65 inch ………..I enjoy the convenience of streaming all kinds of music off the internet usually u tube which is compressed and compromised……currently I am restoring home and setting up a front room for theater and listening and living room . My questions are best way to stream movies ……apple ….roku ……kaleidoscope….idont know ? Listening in 5 channels…….like tribute to George Harrison at royal albert hall in 2001 ….which is a blue ray format or a great 2 channel system as well ……overall I would like to go back to my childhood listening to tube amps but not necessarily vinyl records…I want convenience and choice at my fingertips….I would like to try mostly McIntosch and am willing to spend between 30 and 40 k on used equipment……for video an 85 inch Oled is fine ……speakers 802 or 803 b and W ? I want consultation on buying good used equipment as well as picking the correct components and then also making the room sound good with acoustic adjustments. Thanks again !

sounds like you have a budget to work with a dealer/professional audio installer. For this much money, you can buy new too. The benefit is the return policy, for 30-60 days you can return it no questions asked, You can see a lot of speakers here  https://speakerchoices.com/

but I sure don’t have the confidence to make any suggestions for you in your price range. 

Consider getting a used Trinnov AL16; the DSP and Room correction are top-notch. I have one I bought used a few years back, my speakers are a collection of Wilson Audio, some new, some used, and JBL in the ceiling. I have gone from Monoblocks for the LCR and Multi-ch from the effects. The trinnov does fantastic things with voicing on each of the speakers. The bass management is incredible. I use four subs.
