I see a lot of knowledgeable people here with enviable systems, so this seems an ideal place to ask for advice. Hopefully someone notices and takes pity! So, I realise it's less than optimal, but essentially I'm looking for an all-in-one 5.1 set in the £300 (350€) price-range, but I'm having trouble making sense of the crowd. I've seen the Edifier S550 recommended in plenty of places, but that's in comparison to Logitech sets (which is no comparison at all, right?). Also in my price range is this from Denon which, on the surface, appears technically superior to my untrained eye, and this from Onkyo. I've a Xonar DS currently, but upgrading that isn't an issue if necessary. If anyone can help choose between the above sets or recommended something else then I'll be forever grateful. Thanks so much!
