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 !
