Squeeze Box upgrades


So far I have found two places that upgrade the SB3.Red Wine Audio and Bolder Cable.Which one has the better offer?I'm not to sure on battery power source or Panasonic and Black Gate.

Try www.etree.org. There are some links to free tools there I use. EAC to rip the CD to the HD, then a WAV to FLAC conversion tool. If there is something free-er and easier than that I'm interested in hearing about it too.
EAC can be configured to compress with .flac as the external compressor. It works like a charm and can consolidate the .wav > .flac process.
Is there any difference in sound quality between buying a very good sound card with 24/192 sampling and a breakout to a SB3?
looks like there's a SB3 with the digital mods from RWA for sale/trade here:
