I have never used sacd but was wondering how big the uncompressed file out of an sacd is(Bitrate). Also, Is there a lossy encoder out there that can encode these files and actually do it justice?

What I mean by the word "analog" is that is sounds more like the original master or real life. More bits so that less quantization is needed. In theory, doesn't analog sort of mean unlimited bits and bandwidth since the sound of somebody speaking to you for example doesnt have x samples per second. It is unlimited. All thats done with digital audio is making enough samples per second to make the digital audio sound as if it is the "analog" or real sound that was originally recorded.
The argument is whether the difference of data between 2 channel 16 bit/44khz CD audio and 24/192 really have an audible difference

Yes, analog may be thought as unlimited but your argument is a moot point because we can only hear frequencies up to 22khz (and sometimes even lower than that).
In the past Nyquist already proved that to fully represent the spectrum of a bandwidth limited signal you have to sample at a minimum of twice the highest frequency. Which is precisely the samplerate of a CD.
Going above that smells like snake oil, because for sure it has no scientific base...

Its not the frequency response I worry about, its the number of data bits making the sound "less jagged" like a higher polygon count 3D model for example that makes it smoother.

I don't understand you. huh.gif are you talking about the bit depth?
