The third source element in my music system is the
digital music server.
In a nutshell, all my music files are held elsewhere on my home network. Music is accessed via a
laptop computer and the digital stream is fed out through a
DAC to the
amplifier.
The set up consists of three elements:
Laptop : Currently, this is a
Dell with one or two issues, like turning itself off or freezing after an hour or so ...
Software : I'm getting good results with
Media MonkeyDAC : Cambridge DacMagicThe
laptop connects to the
home network via
WiFi. This means the music files can be held elsewhere so
HDD noise is kept to a minimum. Most files are in .
flac format. This is a
lossless compression format. .
mp3s are
lossy and it's possible to spot the degradation in a .
mp3 file on playback through a reasonable system.
.
flacs have different levels of compression, but this only makes a difference to the amount of processor power the computer needs to decode the file. Since this laptop does little else, it's not really an issue.
Media Monkey both catalogues the music files and processes the digital file for export as a digital stream from the laptop via a
USB port. When the
DacMagic was first plugged into the computer it was identified as a
USB sound card.
Media Monkey can use a variety of output modules. At the moment I'm using the standard
wave output.
The
DacMagic can switch between three different digital sources and has three switchable digital filter profiles. The device converts the digital input to a regular analogue output which plays back through my
Marantz amplifier.
The music source files are either ripped from the
original CDs or, more and more often, downloaded direct from websites run by the artist's label or retailers who are set up for digital delivery. It is possible to find music which is recorded at a far higher fidelity than can be delivered via CD
