From your description of the kind of sound you like, and judging by your preference for the MF B1 and the KEFs, I'm sure you would like the Apogee very much. However you would either have to luck onto a used one already equipped with a USB card (Apogee have discontinued the card) or get a FireWire card for your PC, and then a Mini-DAC with FireWire. That would be well over your budget.
Your tastes are well-defined. Can you get a listen to any of these units? I owned a couple of earlier-model Cambridge DACMagics a while ago and I thought the version 1 was not good while the version 2 was good value. The new DACMagic may be very good, but listening is obviously what will tell you. Alternatively, try to get a 30-day return option if you can't listen before you buy. Failing these, you may need to be prepared to buy and then sell on any units that don't meet expectations.
If you're going to try to choose by user reviews and comments, search the archives here and also try Audio Asylum (the Digital-General and Digital-PC Audio forums ) and Head-Fi. And since you like your Musical Fidelity amp, you might want to add the new V-DAC to your list... ;o)
Wish I could tell you a killer in your price range...
