In Reply to: Looking for measurements about audio improvement with Rasberry Pi 3 CRAAP config posted by Windows X on January 13, 2017 at 07:16:57:
Guys. Read the post with *smiley-face decoder on*.
Let me spell it out:
Bit-perfect digital output sent to a good DAC through an interface which can help reduce jitter (asynch USB, ethernet, i2s...) will not result in audible differences.
I don't care if they call it a Pi, microRendu, NUC, Mac, etc.
I chose the CRAAP acronym for a reason. Like many beliefs in the audio world, we can give all kinds of "attribution theories" about noise, jitter, distortion, etc. If some folks like the sound of the CRAAP settings, so be it, I highlighted some possible rationale.
But objectively, other than the Pi 3 running cooler??? Nah. It just sounds great :-).
Abe: I have read your messages and see you as a reasonable man in many ways. Be reasonable about objective measurements like what I post. It's not tech specs and ideal conditions that is important. It's more like do you honestly think the human ear has acuity when it comes to distortion, frequency response, J-test discrimination greater than what I consider as a very good ADC like the Focusrite Forte? My opinion is it doesn't based on various evidence I have found over time.
If you think that using expensive AP gear comparing the microRendu vs. NUC using the same high quality DAC will show audible noise/jitter/distortion... Or using a linear power supply for the Rendu would change the output of a good DAC, then by all means provide the evidence. Show us the work done and the results obtained. Discuss the significance of this finding and whether there is likelihood of audibility.
Until someone does that, you can be as dismissive as you please. But realize that the arguments and claims remain in the subjective realm. I respect to some extent the importance of subjective reality, but when it comes to debate about whether some "physical" property in the world has changed (ie. the potential for the sound waves to be different and I can potentially hear the difference), I'm not particularly interested in debating without actual evidence.
For the record, I have been asking for this evidence for years. Yet to see any manufacturer, professional audiophile writer, hobbyist actually take on and show me objectively that I am wrong.
