Jitter is the reason why the same digital signal (pattern of 0/1 bits) can sound so very different when converted to analog. And jitter is incredible difficult to get rid off. Let me try to explain why (I will simplify here and there to explain the core of the problem more clearly).

Dear Peter,

As promised I hereby send you my personal findings of the system so far. It took some time because I was busy and I needed time to understand the system better.

I'm not kidding. It's my theory, but I think it'€™s solid. I use no wild speculations in my arguments, and I have seen plenty of evidence.
