How are DAC's rated?
I'm somewhat confused here and in need of a boffin to explain how this works, in layman's terms...
I know what a DAC is and how it works in principle - the bit i'm stuck on is, what makes one DAC better than another?
I have a cambridge d300se which i know has a Crystal DAC, and i have been lead to believe it is either 20 or 24 bit? I've just purchased a marantz cd player cd6000ose ltd ed, which i have been informed was much more expensive to purchase when new than the cambridge i have, yet the DAC on this is only 1-bit?
SO, surely the processing power/speed/other cannot be a good? And if so, why was this player nearly £100 dearer to buy?
If anyone helps me with this i'll buy them a carrot for xmas
