C is the same as B but after also killing the graphics "kiosk" processes, including X11 etc since it would require a screen to be attached to HAKAI anyway.
In my ears, C is best. Surprisingly, the difference is larger between A and B than between B and C.
I agree partially with tokenbrit, "B" is best on second comparison only. First song is still within my margin of error; very little
difference between all three.
Paaf, you may not quite understand the activation and elimination of computer processes. If you start a computer and negate a process, that is different than negating the process and restarting the computer with a process not active. There are several apps that allow manipulation of processes actively. I doubt Volumio offers that. If you are stopping processes during a same session, meaning not restarting, you will not get the same result.
I have done MANY
comparisons between using and eliminating computer processes and have found that though they can
improve the sound, a far
larger benefit was increasing the priority of the primary application.
For example, reduce
the priority of "kiosk" graphics instead of eliminating it. There are often dependencies which allow a certain app to function. Eliminating it changes its' priority.
Think of it this way, a computer can only perform one function at a time. It may perform many thousand functions per second but one sequence often sounds better than another.
Have you listened to your own samples here you've posted online? I think you may be surprised as to what you've uploaded compared to what you think you have heard prior to that.
