Classic research on the effect of cables:
M. N. Kunchur, “Cable Pathways Between Audio Components Can Affect Perceived Sound Quality,” Journal of the Audio Engineering Society, Vol. 69, No. 6, pp. 398–409, June 2021, DOI: 10.17743/jaes.2021.0012
-
This peer-reviewed AES journal paper specifically investigated whether the interconnect pathway (i.e., how cables are connected between audio components) can be audibly distinguished in controlled listening tests.
-
The conclusion was that two audio system configurations differing only by the interconnect cable pathway were audibly discernable in blind listening tests — suggesting that connections and topology can matter more for perceived sound differences than simply cable materials or exotic designs.
