Getting the best from the Squeezebox:
Install Exact Audio Copy
http://www.exactaudiocopy.de/ Configure EAC
http://wiki.hydrogenaudio.org/index.php?title=EAC_Drive_Configuration Install the AccurateRip plugin for EAC
http://www.accuraterip.com/ Install FLAC
http://FLAC.sourceforge.net/download.html Configure EAC to rip directly to FLAC
http://wiki.hydrogenaudio.org/index.php?title=EAC_and_Flac OK that's the hard bit sorted - but you only need to do this once

It will allow you to rip accurately rip CDs directly to lossless FLAC and will use the Accuraterip plugin to verify your rip accuracy with other users.
Next you install and set up the Squeezebox.
http://www.slimdevices.com/su_downloads.html Notes:
Set the SB to use maximum volume on the digital output - you don't want to chuck resolution away.
Set the SB to send FLAC/WAV and *NOT* MP3! (This is actually a default setting I think).
After some experimentation it seems that better sound is available if the FLAC is decoded to WAV on the PC and then streamed, rather than using the SB's internal FLAC decoder. No idea why.
Under server settings -> file types
Uncheck FLAC FLAC (built-in)
This will force the SB server to decode the FLAC on the PC and stream the WAV file.
You can verify this by popping up task manager and playing a file - you should see the FLAC decoder appear in the tasks.
If your wireless network cannot stream WAVs then you should check the option above and stream FLACs instead.
Connect the Squeezebox to your processor and away you go!
Welcome to the future
