System optimizations?

[Skip Pack]

Hi Skip, though I'm not a believer in audio quality benefits from the CRAAP™ settings (and neither is Archimago), I am interested in the power reductions. Do you find any drop in responsiveness when browsing the library while using the underclocking settings?

Thanks,
Richard

No drop in responsiveness that I can detect, but I rarely use the library. I'm on the Browse screen or the Playback screen all the time. As far as audio quality, what I pick up is a slight change in tonal balance, reducing the high mids. It's not any sense of reduced distortion, a blacker background or increased clarity. I have 71 year old ears which have steadily become a little more intolerant of "brightness" over the years. So, my definition of sound quality need not align perfectly with other folks.

Similarly, I have tested multiple resolutions and phase settings on upscaling using SoX on files from the command line. You can see the reduction of CPU load while playing versus the same upsampling done on the fly in MPD. I believe I heard a slight "relaxation" comparing the two regimes that tallies with my perceived difference with and without Archmago's settings.
