Take kind of makes sense! I was worried as I think that might be how Ive stuffed the audio bit on my current system. As I said above, Im only running the 2 front speakers and a sub as I dont have the patience for a full 5.1 set up at home (plus the missus hates the wires), so rather than use the small Samsung speakers for the front, I salvaged by old Sony hi-fi ones. When you add a toddler with a finger on the power button and a hand on the volume knob, you can see where my suspicions came from!
Following on, can you buy just the unit without speakers then? Ive searched but cant find anything.
