Hi, I edited your last to take the words out of my mouth that you put there... 
... make sure when you quote someone that you don't place your text 'between' their start and end quote markers; otherwise, it looks like they said it all , and everyone is wondering what your point was.
I reject the premise of this discussion;. With an 8bit ADC I doubt seriously that you need to take 800,000 samples per second. That might be another discussion.
Have you considered using the MCP3208 eight channel 12bit ADC. ( see mcp320x pdf datasheet )
The mcp320x ( x is the number of channels ) is a 12bit SPI ADC. You might only need the mcp3204. I think 12bit is the minimum I would use ( many applications need 20bit or more ). I have used the mcp3202 many times , and have had great results on both the Raspberry PI , and the PineA64. The mcp320x simplifies the application interface considerably, because it combines the ADC with the parallel to serial conversion for SPI.
