Completely forgot about the Z-10s haha! They have a 3.5mm in for use with a soundcard, but then you don't get the screen display, and I'm not sure if the controls would still work (It's the same screen as on the G15 and Z-5500's and I'm not sure if the volume control would adjust volume through Windows volume like the G15 (Admittedly it's a keyboard,but the principal is still the same), or whether it would manage it itself)


Your call, personally I'd go for the T20's (Or save extra and buy the T40's) but the Z-10's still look like a good buy, however bear in mind that some of the cost of them will be for the screen and USB DAC, so they hold better value for money if you don't have a soundcard and can make use of the DAC, although the one on your X-Fi should be of superior quality.
