Hello Equipment: I have a PC with a Creative soundcard (it sucks! because it curtsy when i play something or when I skip), maybe the PC is a big disturbing source? Doesn't matter. I would plug the PC via USB and the Xbox360/PS3 via Toslink. The DAC should be some kind of monitor...

I'm locking for something like the Beresford Caiman DAC. - 2 sources (PC over USB, Xbox360 over Toslink) - Output with Volume Control for my monitors (EMES Black) - Headphone AMP (with Volume Control) for my Sennheiser HD650 Price: 200-400$ P.s. Or should I buy an USB Audio Interface...
