I've now had the centre and two stations for six years and, apart from the frustrating software problems, the system has provided reliable service with very good sound quality, an ability to hold all of my 400 or so CDs and the facility of being able to access my collection from three locations. Another big bonus is being able to take a station out into the garden at barbeques - or by taking the center, at a guests house as well.
I also play back music through a 'Bose' sound system which is designed for this type of computer based hardware with fabulous results.
It is not for everyone obviously, but for those with a modicum of computer skills it is first class - that said I accept that a notebook laptop will provide a similar result but requires a boot up time and separate speaker system.
