Not that it matters in the least, but the cables will be more exposed to static electricity when in the air insulated from the floor. The better the separating insulation the more chance for static electricity.
Why do you think that static electricity has anything to do with audio electronics?
Oops! I should have written 'meaningful change'.
Of course now with high resolution test equipment, over time, temperature, humidity, voltage and current there very well may be measurable changes in any part or unit.
With the exceptions of vacuum tubes, transducers, mechanical moving parts and some electrolytic capacitors, NO the don't measurably change.
With the exceptions noted above, electronic units don't deteriorate.
As 'Folsom' just pointed out. Short AC cords & cables from hi-fi component to component means short Safety Ground conductors with the attendant low end-to-end resistance and small ground loop area.
Only large home theater or huge power amps need more than one 20 Amp circuit.
Have him run a 120V feeder to a central location in or near the audio room. Then a small breaker box for the 3 breakers.
One size larger cables are always good.
If you are going to use a large isolation transformer (wired as a Separately Derived System) then make it a 240V feeder, but only...
Actually ithe AC power current goes from the big power company transformer down the street, thru wires, cables & cords and breakers then to your hi-fi components after which it again goes thru wires, cables & cords and breakers to that big transformer.
As for 'ground' as in Planet Earth. None...
When you write cable design, do you mean?
Unbalanced analog audio RCA interconnect
Balanced analog audio XLR interconnect
Unbalanced digital RCA interconnect
Balanced digital XLR interconnect
Loudspeaker cable
AC power cord
The needs of each are different and the best design standards for each...
The CE certification is not a set of standards like NEC or UL. It's a statement by the manufacture that tha product has been tested to the applicable standards. And the 'CE' lable is often abbused by some manufactures.
There is not much understanding involved. It's mostly audiophile myths and mis-understandings.
And yes there are 'good engineering practices' for designing any type of cable and each cable type has it's own practices.
What type of cable are you most interested in.
The AC power delivery system is a series circuit. It starts at the power company transformer down the street and ends at your hi-fi amp's input. Think of it like an ordinary metal chain. Replacing a few links in a chain with heavy links, doesn't make the chain any stronger. (while this is an...
Measuring the inductance of a single wire is of little concern, what is of interest is the loop inductance of a loudspeaker cable. That would be measured with the Hot & Cold conductors jumpered at the far end. With the lengths being equal, the cable having the wider conductor spacing will have...
The UL Standard 817 which is only about line cords is 180 pages long. That's a whole lot more than just being stepped on.
Any and all audiophile products sold should meet all the required safety standards.
The RCA interconnect started as a very low cost mono system. There was only one cable per unit. A male chassis mount would look strange and be easily damaged.
Before the XLR, there were other larger male/female interconnect systems. A pro setup can have many cables and it would have been bad...
As above, euphonic colorations and self fulfilling expectations.
But when it comes to real world horn speakers, there are the good, the bad and the ugly.
No, I'm aware of reloading or refreshing a page when going to it from my 'history' list. But anyway everything works OK now. I checked on some of the older threads.
Way O.T.
I do a small speedskating web-page. But even when I do a major update to the index page, some browsers still show what...
