I'm not sure there are any tweaks that improve how the bits are burned onto the CD. Though I have wondered if the act of copying the data to a hard drive and burning it could remove jitter induced during the manufacturing process of the source CD.
It does seem that tweaks to the PC could help if you're doing a/d conversions like digitizing a tape via your sound card. Like a good power cord. Or Vibrapods under the PC.
