Whats a good all around digital cable for under $250. I only need half a meter.

What type of digital cable? If you're looking for new look into WyWires Blue. If you can find a used Silver series that will be better. Alex of WyWires sometimes has trade ins or demos on hand at nice prices, so it's worth a call to see if he has a Silver. 

Kimber Kable makes very nice digital cables too.

Other option is build your own. Check out VH Audio

To be honest, it has NEVER been proven that any well constructed digital cable is inherently better or worse than another. The laws of digital physics must apply. The bits either get to there destination or they do not. I would not recommend spending over $75 for the length you require. If you are needing a digital coax cable I would recommend you buy one at least 1.5m in length. A digital optical cable will be even less expensive.

Thanks for your input but a silver might be to "shrill" on the top for my system. My speakers go to 100hz. I need something that will smooth out the highs, round them off.

Never heard optical. I have 2 Audioquest cables, They sound completely different. The shorter one is too hot on the top end and the 1 meter is more bottom and mid-range.
