Interesting video. The TDA1387 X8 (substitute for TDA1541) module version could be much simpler. Go to Moode Audio and see info on ProtoDAC. Add a power supply decoupling cap of 2000 uF at pin 28 and use output I/V resistors of either 390R or 430R (prefer metal foil Texas Components TX2575). Use good quality PP output coupling caps. Output level will be nearly line level without additional circuit. Also see videos here by Vincent Fong.
I watched Vincent Fong's video. They have developed a full-fledged and wonderful DAC. It's amazing. I always proceed in a haphazard way, so I learned a lot. For now, I would like to check the operation with Moode Audio. ruclips.net/video/RyGhTj5r3Gg/видео.html
