| One thing is that PCM and Sigma-Delta modulation is not like opposite side of the world...
PCM and Delta modulation was invented almost same era... in France...
Sigma-Delta modulation has some advantage over PCM like filtering and such...
Anyway, Sigma-Delta modulation uses much higher sampling frequency to overcome the 1 bit amplitude step...
Even some PCM converters uses Sigma-Delta modulation to acheive better conversion.
It is alomst funny that people do not know shit about Sigma-Delta modulation but say something nonsense like the technology is dead...
Sony and their SACD thingy will be dead I am sure. However, you need to read some books about digital audio to understand what is Sigma-Delta modulation, DSD, and SACD...
There is not too much variation of digital conversion system...
