Or another way of skinning the cat when using your PC as the primary source, especially if the recordings are MP3s on the hard drive, is to use the Digital HIfi link by Xitel. It's a USB device that installs easily and lets you send a digital stream to your preamp. I'd probably buy an intergrated AVR, with pre-outs on all channels. Just make sure it has an optical digital input. Then use the DACs in the AVR. The PC becomes a true music data server, which is what it's good for. The pre-outs insure your upgrade path so that, in the future, the AVR acts as a preamp and surrpound processor only. For now it's enough power. Like some bottom end? Add a powered sub to the M22s. It's cetainly in your budget. You even get easy bass management with the AVR. Good luck.
