My ex father in law was a pharmacist. As he pointed out that 60% still is of the Snake oil origin. Aspirin is a derivative of Heroine and not the Willow tree as thought by some. None the less it is connected and is respected. Aspirin is now a wonder drug. In the UK is it not a brand name as it was a WW1 reparation. Latest thought is 75 mg a day might prevent bowel cancer. I bet if you said that 20 years ago the laughter would be heard miles away.
I was listening to a BBC Radio 4 program. The guy was getting fed up with people criticizing various authors. He said " I have been around the world and have seen many statues to authors. I am yet to see one for a critic".
My point is what is the value of being a cynic?
As to it only being a connector that should be the question. No connector if possible. Preamps were only sold as a way of using a processional power amps at home. Quad might typically sell 70 % power amps to 30 % preamps in the 1960's. It should be that an integrated amp is better. As it is the poor relation in the male jewelry stakes it is rejected. There are other reasons why a preamp might be better. The interconnect is not one of them.
Nope. The only connection between aspirin and heroin is that they were both produced by Bayer.
It is not possible to make a perfectly symmetrical anything if you examine it closely enough. The real question at hand is can these asymmetries be perceived in a sound system. That is not an issue of physics.
A reasonable approach. However the cable distortion at -130 re 10mV is below what most analyzers are capable of resolving. Of course if there really is an issue with using non-magic copper then the analyzers will have to be built with magic silver or magic copper before they can show the distortion.
Hello Ed.
I find it is well worthwhile to attempt perfect symmetry.
They can.
These very low level asymmetries add a 'wrongness' to the overall sound.
Depth information is curtailed, absolute polarity is less distinct, bass wrong, mids hardness, false sheen on high cymbals and sibilants.
Subtle, but the effect is there...once heard, not forgotten.
Can elaborate via PM.

Really low level, subtle stuff, due to wire/cable asymmetry/directivity.
Makes or breaks the sound of a system.
Wire asymmetry/directivity can add an 'excitement' to the sound...false excitement.
Make connections non directive, and correct sound just pops into place (into the air).

Wires can well be directional ime.
Dan.
Balanced cables can have assymetrical parasitics to screen, more particularly balanced cables with foil screen and drain wire....Beldon ? wrote a paper on this.
Dan.
My point was that cables aren't directional because otherwise it would show up as distortion, and it doesn't, and now it has morphed into this. Funny.
If the conductors in a balanced cable do not have the came impedance in relationship to GND then they are not balanced. I have read the Beldon paper regarding drain wires, simple solution don't use a cable with a drain wire, they were used for cables with crappy screens anyway to reduce the resistance without having to spend loads on adding a proper screen, again why use something that is not up to the job if it is going to affect the signal integrity. I would be interested in how much of an affect this had at audio frequencies....
Yes, sorry. I also think he would not be dismissive to either side of the issue. He has sent pictures of the cabling to me and Barrie something to behold.
Don't forget folks that copper and most pure metals have a 3000ppm/degree TC so before you try to extract data at the -120dB level you better be prepared to keep the environment stationary to the .0003 C level.
I wonder how long after handling the cable gets back to the same temperature.
Read my sig, the wide open-loop BW idea is still taken as gospel to the point that one very successful high end designer takes an amplifier with huge BW and slewrate and claims simply resistively loading the VAS to kill the gain and raise the apparent open-loop BW has great benefit.
My point has always been that this idea is wrong, and teaching it to folks that come to learn some basic engineering is a bad idea. Same goes for the sound of feedback.
Before I forget I remain surprised at how rarely the high quiescent bias in the output stage of the O/L amplifier is credited. This was a large departure from the practice of the day and considering the impact on reducing crossover distortion IMO had as much or more to do with the sound.

This affects EMI/RFI immunity, but has nothing in common with "cable directionality". Cable directionality is a nonsense.
