Note: To be able to have different PC's connected through a network you'll need to have Windows XP Professional or Vista Ultimate/Business installed on all computers which need RDC (Remote Desktop Control) for full authorisation to play music from an external PC or network drive.
Several options described below are only possible with the CrazyT, if you use a normal USB DAC then it is not advised to use a long USB cable (data error!) and the suggested Wireless USB network hub option will then not work properly either.
Advantage: No network required, easy to setup, maximum speed and relatively cheap.
Disadvantage: Cables hanging around, no remote control options, Laptop (limited HDD space) or PC (enough HDD space possible) close to the system, usually having audible noise.
Advantage: Remote control options, stored music elsewhere in case of many CD's (less noise).
Disadvantage: Similar to the basic stand alone situation plus a slower datatransfer due to the network maximum speed where a wireless network sometimes can be annoying.
Advantage: No extra laptop or PC required, anything is possible, hardly any visible cables hanging around (even a wireless mouse and keyboard can be connected to the same Network USB hub), no noise whatsoever disturbing the sound (the PC is 100% isolated from the audio system!) and everything on the computer side can be changed, replaced or updated without any negative influence to the audio system itself.
Disadvantage: More expensive and no functional remote control unless you use a laptop or other (small) device like a smartphone which is connected to the network (usually wireless) with RDC installed to control the main computer. To be able to use RDC you'll need to have Windows XP Professional or Vista Business (or Ultimate) installed for full authorized access.
