...So while one may disagree with the orig poster's choice of how to qualify better or worse (ie "bright" etc), it doesn't make sense to say that the prime mover of the modulated groove and it's carrier, the cabling, cannot affect the sound.
Saying the power cable is out of the signal path is a bit like saying that railroad ties are in fact, out of the train's path, since they cross it underneath, and don't actually touch the rails; would anyone argue that they're not a factor in rail travel, by virtue of being once-removed ?
Just saying. Welcome to the internet, and its wonderful Inviolable Advocacy Of Opposites. Agree to anything and someone else will post a message to tell you it's frankly impossible and never happens.
2012. Same as it ever was.
Advocate all you like JD, but at least do it with some logic and honesty.
Here's what I first posted - note the qualifier:
"It means that the op thinks that the power supply cable, which only feeds the motor and hence is not in the signal path somehow influences the output signal (outside of characteristics associated with speed stability).
This is, frankly, twaddle."
Your attempt at an anology to railways is, well, forced. The railway ties are an essential item that allows the train to bear evenly on the track and its substrate - a more fitting anology in the turntable might be the plinth.
Yes, you could I suppose consider the turbine to be in the audio signal path - but if there ever really was a case of reductio ad absurdum argument, thats it. If you feel that the motor supply IS in the signal path, then so is the ceiling light in the room - in fact the street lighting outside too, and any other device connected ot the same turbine.
You are right, many things are "notable" for effects. Unfortunately, the majority of them are not reliably tested and proven to have an effect - its just taken at face value that because someone (often the maker) says it is so, it is. Where its not the maker, its often an unqualified individual making a claim that (surprise!) back a hypothesis that they have previously mooted. This claim is then reinforced by a group of, and here the only word I can think of that is polite is "unquestioning", supporters.
In large part, I am applying a test of reasonable causation - is it reasonable to expect that a competently engineered power supply cord would have a negative impact on the sound output of the turntable? The answer of course is no. There is no good logical scientifically based engineering reason to beleive it.
The prefered way to believe that the power supply cable is the cause of "brightish" and "forward" presentation in a turntable is to apply pseudo-science and develop esoteric explanations of causation. It helps to misinterpret or more commonly completely disregard basic physics.
The alternative (offered in this thread) is to offer a total lack of hypothesis of causation - just accept that the miraculous has occured as an object of faith.
Sorry guys - but you need to be in alt.religion (or alt.mysticism)if thats how you roll.
In summary - I disrespectfully disagree with your statement that "...it doesn't make sense to say...the cabling, cannot affect the sound". For any reasonably capable cable it makes absolute and complete sense.
