Q. How much more space would be involved to leave the files as WAVs?  
   How would that effect the use of the AudioTron?  
   What tag information would be lost? 

A. A ripped CD in WAV format takes the same amount of disk space as the
   original CD.  In other words, if it was a full 74 Minutes of music, it will
   take 650 Megs of space per disk.  Since those files are so large, the
   effect on the AT would be, in theory, a greater chance of music slow-down /
   drop-out due to network or server congestion.  It would place a good deal 
   of traffic on your network during operation.  

   The other drawback of WAV is no Tag information. Just the title of the
   filename on your server. Not very nice for searching your collection….
 
   You should try to convert them all to the highest bitrate MP3 or WMA files 
   you can.  The latter will give you the best space conservation and sounds
   surprisingly well.  In addition to the space savings (roughly 90%), you
   will have less network traffic and chance for drop-out during playback.

More on WAV files:

   WAV Files are uncompressed audio. Standard Audio is recorded at 44.100 
   samples per second. 16 bits per sample. 

   Multiply 16 bits times 44100 = 705,600 bits per second. 
   Divide this by 8 to get bytes = 88,200 bytes per second. 
   Multiply that by 60 seconds and you get 5,292,000 bytes per minute. 
   Divide this by 1,048,576 (1MB) to get 5.04 something. 
   Multiply this by two in order to get stereo and you are looking at slightly
   over 10 MB per stereo Minute.
