I have no loudspeakers connected to my desktop whatsoever, just this big receiver whose speaker amp I need to drive my Stax Lambdas.
Ever since I learned how to set up CMSS-3D Headphone just right and get precise, convincing binaural surround sound out of games (especially with the right headphones), I stopped caring about surround speaker setups for the time being. I just don't have the room for it (gotta acoustically treat everything and place those speakers just right), and I don't live alone, which means I don't need to annoy other people in the house with the sound, especially later at night.
On top of that, I don't think I can get any speakers that come remotely close to the sound quality of this vintage Stax setup for $250 or even $500. (Admitted, I got lucky getting this setup for such a low price, but the point still stands. Heck, most Quad ESL pairs go for around $2,500 these days.)
