Ah! So it needs another unit to do its thing. It's a pretty big unit, do you think it's going to make a big difference in listening experience? Thanks for the reply by the way. First time here.

i just got a 1983 jvc turntable and my dad has a sansui qs 500 rear receiver. Now I'm going down the rabbit hole and want the quadrophonic sound experience. Can any stereo amplifier work with the rear receiver? Do I need sansui 5000a or better? They are hard to find in good shape and expensive...
