At least this thread enabled me to learn something. But confirm something I had already thought.
Cables and connectors can sometimes effect final sound quality, but I do not believe there is a need to spend huge amounts of money on connectors. Just buy adequately good ones.
The $2800 ethernet cables have fairly economic connectors that cost retail €20. The cable is rated at Cat6e, which is good, but better cable can be bought more cheaply. I saw a Cat 7 connecting cable at €53. I personally find it absurd that this connector, costs more than what I paid for my Naim XS3.
There are a good number of studies that confirm that we hear what we want to hear. If we expect a sound improvement we will hear one, especially if we have spent a huge sum on a cable. I think this is a pretty well known and accepted concept. There are many web articles about this and there are scientific studies if you wish to delve deeper.
Google this medical paper: Beyond the Sound Waves Emilian Kalchev
It takes a look at the Physiological, Psychological, and Societal Domains, that have a bearing on what we hear. I have read it, and those who believe a €2800 connector is better than a €10 connector should do too, reflect and then make up their own minds. It is clearly written for a lay reader.
The paper was mostly about “Burn In” but it concluded
The phenomenon of audio burn-in sits at a fascinating crossroads of empirical science and personal experience. While debates continue within the audiophile community, it is evident that our perceptions are shaped not just by equipment mechanics but also by our unique auditory physiology and sociocultural influences. By appreciating these complexities, we can foster a more comprehensive understanding of sound perception and its implications.
As one returning to HiFi after a few years away. I am very curious and perplexed about the utility and benefit of these very expensive accessories. I believe one of the causes that is causing the decline in interest in HiFi is the huge sums we are told we need to fork out to listen to music. I realise my €10,000 system is Pauper Fi, but I love the music I play on it and how it sounds.
PS. I have not engaged in personal attacks in my posts, unlike some who responded to me.
