Here we go: The relevant issue in this thread is whether RB has better audio fidelity/quality than OF, or not.
Now it is getting highjacked into a side contention about bias, etc.
Do not worry about hijacks. If one of the moderators believes this thread has been hijacked, he will lock this thread.
In any case: ABX itself is frequently questioned by evaluators as a source of inaccurate results.
Examples? Do you have any citations from credible sources that believe biased evaluations are superior to ABX evaluations?
For example, people who would like to believe that $10,000 speaker cables improve sound quality will claim that the ABX connections themselves “color” or otherwise affect the result, therefore the ABX result showing no difference with $10,000 cables is “invalid”./
A more plausible explanation is that no differences were heard, because there were no differences to be heard. Anyway, this theory has already been tested by physically swapping wires.
Earlier I wrote: “There is a way of verifying whether you are more or less biased. And that is to observe how you do in an ABX test. Many individuals have claimed to be able to hear a difference. Many of these same individuals have, after an ABX test, shown that they were not able to hear a difference.”
/That would be a way to verify to OTHERS whether I am more or less biased.
Yes. It is also a way to verify to yourself whether you are more or less biased.
If an individual had no way of discerning better-sounding audio output without doing an ABX test, the entire field of hi-fi would never have started.
Yes. But we now do have access to ABX. And using ABX, audio researchers have developed lossy formats such as MP3, ACC, WMA, and Vorbis.
Really, it mainly boils down to “honesty” and seeking the truth in reality experienced, as an inherent discipline (or not).
High-end audio often vilifies ABX. And honesty is definitely not a word that is associated with high-end audio. It does not boil down to honesty. It boils down to properly evaluating sound quality. From The Audio Critic: “We believe in measuring and we believe in listening but we don’t believe in measuring with our ears.” If you are sincere in seeking the truth in reality experienced, you will be better off looking for objective data and trying to understand why ABX is superior to biased evaluations.
Many people have difficulty separating their wishes (or ulterior motives) from the truth, so much bias comes from this.
This is why the vast majority of high-end-audio “reviewers” hate ABX.
Sometimes it comes from wanting to feel better about their selection (e.g. $10,000 speaker cables, RB, etc.), sometimes it comes from dull senses, and sometimes it comes from wanting to fool other people (e.g. wanting to sell those $10,000 speaker cables).
Earlier I wrote: “So far I have yet to see any objective data presented in this thread.”
/Depends on what you mean by “data”. Do we need a test report from a certified accrediated third-party lab using NIST-traceable equipment, costing thousands of dollars?
Please see message 8 in this thread for a hint at the possibilities.
Or can we consider information such as posted by mroberts200?
I prefer technical tests such as the ones I stated in my previous post.
We have no way of verifying the veracity of information posted here; pretty much anything you see posted here could be fabricated.
This is the point I was trying to make in my previous post.
But I consider it in combination with my own hearing, and other posted subjective opinion, and so far they mostly agree.
“We believe in measuring and we believe in listening but we don’t believe in measuring with our ears.”
Whatever. Hey, if someone prefers RB, that’s great. As for me, I hear a difference - RB is inferior sound quality - so I will stick with OF./
Earlier you wrote: “The OF sounds clearer; I can hear both lower and higher frequencies more clearly, less distorted sounding, and more detail within the music.” It will be interesting to look at the total harmonic distortion using the different firmwares. To me, SanDisk’s firmware sounds as good as Rockbox’s firmware—no signal processing activated.
