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.

EAC can be configured to compress with .flac as the external compressor. It works like a charm and can consolidate the .wav > .flac process.

looks like there's a SB3 with the digital mods from RWA for sale/trade here:

Maybe he needs money. Maybe he is in trouble with his parents or wife who just got the credit card bill.
