I currently am using the logitech X540 which i bought for £40 3 years ago , there working well but i am tempted to upgrade but would like to know if its worth it or not. I have a budget of ~£120 and a xonar dg sound card, reason i feel like upgrading is i recently found out that whilst i thought my speakers were defective apparently they are not true 5.1 as the centre and sub channels are mixed, would i benefit from better speakers or should i just forget about it.
.

. problem is i wont have the room for big speakers like those and have no idea about compatibility, brands etc. Any insight would be welcome however.
