Equalizer APO is a great one. But I don't think it has been tested with windows 10 yet.

If you haven't already dug around Windows yet, it does have it's own built in EQ

I remade the list. Now it's a little different. So I curious about your opinion of it. https://listium.com/@Tomas088/45610/digital-mixers
If you like it, feel free to make your own copy of it and use as yours.
I did some Amazon looking, do you think this is the proper one for microphone audio? Wpeng 3.5mm 1/8" Stereo Male Plug to RJ45 Female Extender Over Cat5&Cat6 Socket Ethernet Adapter Cable(3.5M/RJ45F) https://www.amazon.com/dp/B01MFAHOOL/ref=cm_sw_r_apan_glt_fabc_8ZB95K78XDHEQQCJV3DV
This is one I found. It has a coaxal port on it that says digital audio in, but it also has speaker wire hook up. Does that mean I can hook up either or.
Look at picture 2 on Amazon
Denon AVR-S540BT Receiver, 5.2 channel, 4K Ultra HD Audio and Video, Home Theater System, built-in Bluetooth and USB port, Compatible with HEOS Link for Wireless Music Streaming https://www.amazon.com/dp/B07C49F2LD/ref=cm_sw_r_cp_apa_i_yw5UCb4C1GC4T
You need a standard IEC cable. Like these
EDIT: If you don't live in the US, you'll need to get one with the appropriate male end for the plugs in your country.
