Our Verdict
LG S90QY
LG S75QR
The LG S90QY is better than the LG S75QR for most uses. The S90QY is a 5.1.3 setup that's more premium and comes with an additional up-firing center channel. It reproduces a more extended low-bass and has additional features like Wi-Fi support and room correction. Without satellites, though, it doesn't bring as clear or real of a feel to surround sound. You can always upgrade it to the LG S90QY with SPQ8-S Speaker Kit if you want.
