X-Fi bought, now, what speakers?

[Xon]

Hi all,

I just bought an X-Fi and am using P580 5.1 speakers.

Do you reckon I should change these speakers to do the card justice? And if so, can you recommend between the Z-5500 and the Gigaworks S750? 7.1 isn't important I don't have place to set it up so I'll end up converting to 5.1 anyways. How do the Z-5500 compare? I know they're digital but I have one of these http://www.soundblaster.com/products/product.asp?category=1&subcategory=16&product=14191 to make up for that

EDIT: Nvm the digital part I'd be using the analogue passthrough.

I'm not interested in digital tbh. I will connect the Z-5500 using analogue connections... reason: optical out on x-fi afaik will output a raw signal out... no proccessing on it is done. So to get 5.1 in games using eax the only way is analogue out - The decoder of z-5500 is going to waste in my case.
