Al & Steve,
Yes, Al, I read the Wiki piece before but was somewhat unclear until you have now further explained it. Visual aids--graphs, charts, schematics are difficult. I need to learn first the meaning before they make sense. I was unclear on the voltage being a constant value and on the transition period as it relates to the binary data.
I was struck with the beauty of the S/PDIF system where the clock and data are one signal until I read Steve's explanation of jitter and how the BMC signal is vulnerable to it.
I'm very happy to have learned this basic concept of the digital signal. Many thanks for hanging in.
Al, on an unrelated topic discussed in a former thread which I should discuss in a follow up to that thread but since the website made changes nothing works on my pc the way it did and I'm not sure you would find it on that thread, and in regard to your lack of enthusiasm for autoformers in SS, I did demo the autoformers with the hk990 integrated driving the AR9's. the 990 is rated at 150w/8ohms, 300w/4ohms, and the 9's are rated at 4ohms. So using the 4ohm tap gave the set-up 150w/8ohms versus 300w/4ohms without autoformers. There was no apparent difference except that sound quality was a little better without the autoformers apparently because of running the signal through another device with more connections. It was a horse a piece.
But with an amp that is limited into 4ohms, the autoformers did enhance sound quality when the amp was driving 4 ohm speakers turned into 8 ohm speakers. Presumably converting 8 ohm speakers into 16 ohm speakers would cause more loss than gain. If all this makes any sense.
