Home Digital Music Server Systems ---
Circa January 2008
I am currently using two 'Music Server' Systems. Both are capable
playing Internet Radio Stations or playing music files (mp3 files) on
my local home computer --- which is a Shuttle Zen
ST62K. To get a little better audio quality on my desk top I use
the M-Audio
Transit to get digitial out to a TOS link which I feed into a set
of Edifier
S2.1D powered speakers that has digitial input. I am a bit obsessed
with getting the bits as close to my final output electronics as
possible. The M-Audio transit is a bit dated now ( IMHO) in terms of
A/D's, and I am not happy with the lack of driver development from
transit. That said, it still seems to work. My goal in these projects
is not 'audiophile'
quality, but the getting good quality at a resonable cost at least to
the amplifier stage. IMHO a good, easy to use internet radio/music
server, is still a huge oppurtunity waiting to be solved (at the right
cost point). This page describes some of the ways I come up with so far
to achieve this ..., as I mentioned getting (say 24 bit) direct digital
output to the amps seems like the most cost effective way to get good
audio quality for these systems. Both systems are 'wireless,'
transmitting music through the standard 802.11 b/g.
To see some of the radio stations I listen to check out: Nick's Internet Radio
Links
To see some of the folks in my mp3 song collections see the bottom of
the web page here.
The first system I put together is built from a commerically available Roku
Soundbridge M1000.
I us the TOS optical out
of the Roku and run it into the digitial input of the
receiver/amplifier shown below. Roku uses a simple remote and display
to sort through the music or stations. The interface is pretty minimal
but gets the job done for simple tasks.

The Soundbridge is at top and is controlled by the remote on the
right.The optical link goes into the AV receiver below --- I was unable
to find a good quality (resonably cost) stereo receiver for digitial
input, so I settled for an AV receiver even though I use it mostly for
stereo. Here is a close up picture of the Soundbridge.

Here is a perhaps nicer darker image:

Downstairs I converted and older IBM T20 Lab top
to use as a music server. I use a USB out directly into another AV
receiver that has a USB in link, again a direct digitial connection to
the amplifier. The computer is on the left and the amplifier on the
right.

Here is a close up of the amplifier (JVC RX-D206) with the
USB input shown on the lower left. I can send music to different parts
of the house using the switching box above. Again, stereo would be
fine, but I could not find a 'stereo receiver/amp' with digitial inputs
at a resonable cost, so this compact JVC unit seems to be an ok
comprimise.

Here is the display I put together on the T20 notebook computer. By
using the remote you can flip through and play different internet radio
stations. I also often control the system with Windows Remote
Terminal Server, which is about the only piece of Microsoft
software that seems to work well I've ever used.

I had a 'Firefly'
remote from another project sitting around, so I use that to control
the internet radio system remotely.

That's about it. Actually, I probably spent more time building these
systems than using them so far. Still, if you have a old computer
sitting around, and get a receiver with direct digitial input, it is
not too costly or expensive to build a simple music server to provide
internet radio or play your local music files. Alternatively, you can
get a higher quality A/D and doing something similar, like I've done
with the M-Audio transit for my desktop system.
If you want to take your music around with you, I also built a wireless
boombox with my assistant Albert Ryan --- here is a link to that
project: Wireless
Boom Box Project from I think sometime in 2006.
