Firingsquad heeft een review gepost van de Creative Labs (of Cambridge Soundworks, whatever je het wilt noemen) Four Point Surround 2000 speakers. Dit zijn zogenaamde digitale speakers (met de D/A convertor in de speaker zelf):
The first thing I noticed when I made this connection was the immediate absence of any background noise or hiss, even with the volume set to max. To check that the volume control for both analog and digital audio produced similar volume levels, I played an mp3, or should I say, I felt an mp3. I had forgotten to turn the volume control back to a more conservative level. Needless to say, the volumes for both sources was very comparable, this made side my side tests of digital versus analog audio very simple, more on this later.
Many of you noticed that your audio CDs sounded better when you attached the digital audio cable from your CD-ROM to the SB Live!. This is a similar technique that is used in the FPS 2000. Great sound quality doesn't only depend on the method of data transport, however, since the audio must at the end be converted to analog, the digital to analog converter is also of utmost importance. Much of the sound improvement that was seen with your audio CDs was due to the higher quality digital to analog converters in the SB Live!, versus your CD-ROM.
