Yeah, because you know what I realised today? I made a thread about it.
My Direct connection from my X-FI to my z-5500 sounds terrible! Just sounds closed, etc.
Yet, I ran it through Optical on the Xbox 360, and music sounds perfect!
So, I'll have to some way, using my Xtreme Music, get that 3.5mm to Coaxial thingy...
But yeah, I bet you, that'll sort my sound problems out.
If it doesn't, I'll be getting rid of my X-FI X-Music and maybe upping it, or something, to get the Optical
