The Apogee Wyde Eye is a very good digital cable that you should be able to get for about $60. The Stereovox XV2 is also an excellent cable (I own them both), but it is a little leaner sounding and your desire to avoid silver makes me think the Apogee's slightly fuller presentation might be preferable. For 60 bucks I think the Wyde Eye is a great place to start, then you can have fun comparing it to much more expensive cables to see if they really offer something truly better or just different. If it's the latter, you'll have a lot of $$$ left over for music or other upgrades to your system.
Best of luck.
