I don't believe wav is a stream-able protocol.  The metallic sound is more an artifact of compression than the protocol used.   You might try bumping up the bitrate and/or adding a lowpass filter to strip off the highest  frequencies,  this is commonly done with stream encoders.  I've added a lowpass filter to remove PL.  I imagine you could do high pass the same way.   Here's what I use.

outstreamcmd=/bin/sh,-c,/usr/bin/lame --preset cbr 24 --highpass 0.2 -r -m m -s 8 --bitwidth 16 - -  | /usr/bin/ezstream -c /etc/ezstream.xml

I understand. Some people just don't like a "metallic sound". I'm not sure what other options
are readily available. Certainly if you want more of a "dubstep" sound, perhaps you should
pipe the stream through something like "zcat". That would certainly make it more "dubstep"-like. :-)

Seriously, I don't think any of those streaming server things will accept anything other then mp3 (or ogg)
Believe me, it was *not* done by any of my choice (being that mp3 is certainly *not* my favorite
codec for ANYTHING!).

I would like to just publish the basic URL and port (http://localhost:8000). We used to do this with a Windows Media Server before consolidating on one Linux server.
