Cable Pathways Between Audio Components Can Affect Perceived Sound Quality

[pkane2001]

Fully balanced and single-ended signal paths are sufficiently different internally that any differences could be due to electronics rather than interconnects. The author is, unwittingly, changing too many variables by comparing balanced to single-ended interconnects to make any conclusions about just the interconnects. Different components, different signal path, different processing of the signal between these two cases, possibly different signal levels at the output. All of these are important to eliminate as possible confounds before declaring that interconnects cause the differences. 

 

Also, the fact that balanced vs. single-ended can produce different levels of noise at the output is not surprising, since these were created specifically to deal with noise.

I do wonder whether anyone has actually read this paper - just try perusing the Conclusions section, okay?

 

When people have an agenda, all forces that can be applied will be applied, no matter how feeble they are ...

 

Understanding why and how things work is my only agenda, Frank. I understand that you just naturally come by the understanding and knowledge of how things and work and how to improve them. Not all of us are this gifted, so some of us actually need to ask relevant questions. Okay?

No. First step, acknowledge that there is "something going on" - don't apply maximum effort to convince yourself that that you were deluding yourself, by doing measurements until absolutely "nothing to be seen here" - in some parts, they call this being open minded; and they don't let their brains fall out, BTW, when doing so, 😉.

 

The "why" and "how" comes later - accept the WTF'ness of the situation, and proceed with the realisation that something is happening, and should be dealt with ...

 

Not how science works, I'm afraid. We are discussing a scientific paper that purports to describe a scientific experiment.

I started watching and paused it once he got into talking about 'beliefs'. A complete red herring.

 

Curiosity got the better of me and I played a bit longer. Had to stop though where he claims 'wire can't add noise'. I take it he's never heard of 'common ground impedance coupling'.

Or perhaps he is simply saying that a wire is not an active component and can’t generate noise all by itself. Noise can be introduced from the outside, but not generated by the wire.

Not from the circuit in the case of triboelectric effects, no. Its definitely from the insulation over the wire.

But still this comes from outside the wire. Other than thermal and 1/f noise the wire isn’t introducing any noise by itself.

Ah maybe we mean different things by 'wire' - I am meaning the whole interconnect, perhaps you only mean the copper conductor part.

Triboelectric noise is not caused by the interconnect, conductor or insulation. It’s caused by the mechanical motion or vibration coming from outside.
