Converting LP's and other analog media to CD's

I know this discussion might have been started before, but still. I have started to think about converting my analog to CD's. I have done some research and have come across the Alesis Masterlink 9600 modified by BPT and a few others as well. I have read the review in stereophile as well.

I am now thinking of getting that BPT modified version, but before I do that I would like to know if there is a way to upgrade the stock ADC and who does that.

Please share you experiences, methods and best practices.

Happy listening
