I know frick all when it comes to audio side of things, so this may seem like a "duh" question to some of you....

Setup is PS3 and XboxOne connected to a set of Logitech Z506 speakers.

Will buying something like this make any difference to the sound at all ?

Yes/no answers are fine for my needs :-p

I do want to get a proper amp and speakers but the way this year has started, it'll be quite some time away...

TIA
