I'm looking around for a set of speakers, nothing definite yet as I'm on holidays next month and just bought a G25 wheel.
At the moment I've got my MacBook connected to Soundsticks (original USB ones, not Soundsticks II), and my PS3 and 360 connected to some PC 2.1 speakers bought for £20 some time ago, probably back when I had a PS2. So I'm looking for a set that I can connect all 3 into, and be able to switch between them. I don't mind if they're 2.1 or 5.1, 5.1 would be nice if they are the right money.
I've seen Logitech Z5500 as having multiple inputs, but not much else. I'm not much of an audio techie, but the PC speakers are connected (through a not ideal arrangement of adapters) to the red/white audio plugs on the consoles cables (the Xbox is connected through VGA to my Dell 2407 screen, the PS3 by HDMI with a DVI adapter, and the Macbook shares the HDMI cable with adapters (adapters are my friends

), and the MacBook Soundsticks are USB as I said before. Would new speakers use the red/white connectors or a digital connection to the Mac and the consoles, or something else?
Any suggestions or recommendations for the speakers?
