I'll take that as encouragement to make a few more observations.

If you are serious about sound quality, you want a S/W + H/W solution
that is dead reliable in playing without pops, gaps or glitches.  You
don't pay money to get a music-on-hard-disk system that does play
perfectly.  That isn't easy for a user-mode program like Softsqueeze. 
Every now and then Windows may do a blizzard of disk I/O to save its
state. Firefox produces periodic disk I/O storms too and Slimserver may
rescan the music folder at intervals producing its own disk I/O storm. 

The web has a number of little communities of audiophiles who mostly
agree on a technical approach.  USB based DACs are popular on several
of those communities.  The isochronous method of transfer theose USB
DACs use is not a good starting point for high-quality audio.  (No
re-transmission, clock is ultimately derived from the USB traffic,
etc.)  However, Windows provides a builtin driver for that method of
audio data transfer. There is a right way to do it, but it requires
writing a kernel-mode audio driver for Windows and then building a USB
DAC that talks to the new driver.  Nobody has done that.  Instead, they
do more-or-less heroic efforts to work around the limitations of
isochronous transfer.  

The Squeezebox connects to its server via an Internet via an Ethernet
or Wi-Fi connection.  It does the job right: data can be re-transmitted
if necessary and the all-important word clock can be generated in the
Squeezebox with very low jitter.  And the DAC is outside the
electrically noisy PC environment with its own power supply.  So the
Squeezebox might produce better sound quality for $ 250 than a USB DAC
or an high-quality soundcard. You might still use a Squeezebox with a
PC in the same room as your stereo.
