For anyone taking this as inspiration, I would recommend spending good money on a comfortable ergonomic chair and a decent headphone setup instead. 95% as good as an S-tier speaker and room setup, for about 0.005% of the price, and you can go from nothing to audio bliss in 6 months or less instead of 60 years.
