Title: Kunchur again, cables
Post by: ajinfla on 2021-06-07 10:54:27
Milind takes on yet another believer subject, stunningly discovers possible differences between XLR and RCA with, umm, "unconventional" listening tests. Speed read this morning.
Cable Pathways Between Audio Components Can Affect Perceived Sound Quality (http://Cable Pathways Between Audio Components Can Affect Perceived Sound Quality)
Quote
The arena of highest fidelity in music reproduction, sometimes referred to as high-end audio, has many controversial claims and contentious issues. One such controversy is whether the cables and topology used to interlink components together make an audible difference. There seems to be a disparity between anecdotal experiences reported by audiophiles and published formal scientific research as to theminimal changes in system configuration that can be audibly distinguished. With the motivation of bridging this divide—which may originate from differences in instrumentation and subject-listening conditions used by the two groups—this work utilized a high-performance audio system and extended-duration listening protocol that more closely resembles audiophile auditioning conditions. With these measures the present work was able to prove through direct psychoacoustic testing that two different analog-interconnect pathways can be audibly distinguished.

The author thankfully provides a preprint version (PDF) (http://boson.physics.sc.edu/~kunchur//papers/Audibility-of-cable-pathways--Kunchur.pdf) on their academic homepage (http://boson.physics.sc.edu/~kunchur//Acoustics-papers.htm).

How does one respond to such a claim?

Thanks for being so understanding about the concept of gatekeeping.

Tried via AES but comment not showing..
In Sect 3.2, he states that its NOT FR, but "at the level of HEA", time domain issues. The evidence?
Temporal Decay: A Useful Tool for the Characterization of Resolution of Audio Systems? - zero listening tests...
and the infamous Reiss  - A Meta-Analysis of High Resolution Audio Perceptual Evaluation, cherry picked by a Hi Rez peddler (LandR). The highest weighted paper being a ghost paper by BS that was never published. “Further Investigations of the Audibility of Digital Audio Filters in a High-Fidelity Playback System.” There is no conclusion by Reiss about time domain. He then goes on to cite his own erroneous tests.

Thanks for being so understanding about the concept of gatekeeping.
You're welcome

From my limited insight and understanding AES lately arranged with the need of HiRes as a major factor keeping the business alive.
There are proofs like this legendary meta analysis and MQA Bobs own constructs that no one seriously takes in question anymore.
