I used to have so many I put my PC on a UPS. Had one nuisance trip in last year (storm) and one where I had to store my scope in the shed and when I bought it in on a cold evening there was some condensation.
The delighfully kooky Ben Duncan, when doing work for the snaky Russ Andrews did claim that certain breakers, if they ever tripped never sounded as good afterwards. I almost wish I had kept that article...
But for a bit of fun, lets throw 'technical earth' into the mix. Are there any cases where a nice big copper busbar to terminate all your PE connections to makes any sense (assuming your local wiring regs even allow it)?
My Dad is similar age...I trust his ears too.
The 'Father' of designs can be the best constructive critic.
It could be argued that the designer listening is a form of sighted listening and therefore invalid.
It could also be argued that the designer is the best listener for discerning fine differences between examples.
What do you mean by designing for better 'sonic'...harmonics ratios perhaps when you have distortion down to ok levels ?....what are your criteria ?.
Ok, you hear differences in your own designs....I have always heard 'house sound' differences between manufacturers...and this realisation has led me through a long and interesting and fruitful voyage of discovery.
There is a lot more to 'sonics' than most realise.....standard audio measurements are essentially useless when differentiating 'blameless' systems.

Using other listeners is not an uncommon practice, but it has no bearing on the issue of proper blind tests versus the common ersatz substitutes for blinding the masses.
Listening test rigor is not mission impossible. Once you gear up for it, it is pretty easy. Using poor listening tests to guide you makes no more sense then using a voltmeter that randomly reads 50% high or low.
If the listeners are competent they have their own ways to turn any proposed comparison into a proper listening test.
When it comes to listening tests why waste your time on anything less than the best?
Hi Marce, we all understand your depth of skills re layout and EMC considerations and that all of this is based on tested theory and measurements.... we all get that.
What JC and others including myself are saying is that even when getting down to vanishingly low distortions, there can still be a still a 'signature' that differentiates otherwise perfectly measuring equipments.
This 'signature' or 'flavour' can be the long term deal breaker or deal maker....just ask the wife in the kitchen 😉.

I trust the system far more than myself. Some years ago I repeated some listening tests that I used to be able to ace and came up random guessing far too many times. I learned from that.
But there can also be "Constructor's ear".
A proper listening test is proper no matter who does it.
You can argue what you want, but if you want to know the truth you test each circumstance the best you can.
The above statement has a serious problem - often there is no single person who designs everything in a product. It is a fact that many modern systems have become so complex that no single person is likely to have the required skills to design them from start to finish.
The easiest, often most logical design goal is sonic transparency - the product has no discernible audible signature of its own. Now the heresy for high end audio true believers - sonic transparency is often achieved in fairly inexpensive and even sometimes dirt cheap audio gear.
Two words: Sighted Evaluations. Single Blind tests are often not the least bit better.

Thanks I can keep you updated as I get progressive feedbacks.
The deal is that I have profoundly changed the backline stage sound of the band for the better...cleaner, clearer, better instantaneous dynamics/nuances, more extended highs, lows that emerge from below the floor, in short a transformation of the instruments sound.
Ok, so of course the band are in on what's going on, and are are going to play differently because their instruments sound different/behave different.
This combination/resultant new sound is certain to elicit new reactions in their discerning and paying German audiences....this is a whole new sound (lack thereof actually) that is going to cause some head scratching, lol.
Last Fri night here in Perth was the hugest and fattest live sound any of us has ever experienced.....the Krauts are next, haha.

Hello,
Dr AIX posted this joke ad sent to him on his daily blog. Pretty well done and far to real for comfort.
"DH Labs introduces
Gravitationally Compensated Audio Cables
If the moon’s gravitational pull has the power to move entire oceans, imagine what it does to the tiny electrons traveling through your audio cables. In light of this, DH Labs has created the world’s first gravitationally compensated audio cables. By using proprietary electro-gyroscopic technology, DH Labs has defeated the laws of physics, and the results are spectacular. This new technology necessitates maintaining a double inventory, as all cables shipped to the southern hemisphere must have their conductor strands wound in the opposite direction. Price: $7000 per meter.
Wait, there’s more:
To make the best even better, our Earth MFC (Magnetic Field Cancellation) option can be added for only $30,000. As the name implies, Earth MFC cancels the negative effects of the earth’s magnetic field, using precision calibrated magnetometers coupled to proprietary monitoring circuitry. The monitoring circuitry is necessary to maintain calibration should the planet’s magnetic poles ever reverse.
The net effect of these revolutionary new technologies is the purest sound ever heard."

Of course not. You can be objective about their age, though. And their height. And their collar size. Like Max, you are confusing "Do I like this sound?" with "Is this sound a reasonable reproduction of that sound?".john curl said:
Problem is you see these carcasses in every post written by anyone you perceive as hostile, whether they are there or not. Which gives you the opportunity to respond to them again and again and .............
In Arnyworld posting something which could be of some interest to other posters and asking for comment is automatically perceived as a stinging critique of DBT and an overt sales pitch for high end audio from a shill in the payment or control of some unscrupulous ........ you know the script. Providing yet more opportunity for endless repetition.
Bonkers.

Good to see that you are paying attention 😉.
I have just spent some time across the street with my neighbour with my front door open......we both agree the Fri night recording is the most fun live recording we have ever heard.
Dan.
Yes, but it doesn't replace the Safety Ground/Protective Earth and it's not called a 'technical earth'. Ralph Morrison and Henry Ott (along with many others) write about it.
I have to take the grand-kids skiing now, so will be back tomorrow with all the acronyms.
But for a quick description, go 2/3 of the way down the page.

Inside studioland(tm) an audiophoolville(tm) It IS called 'technical earth', which is why I used that term. 🙂. I agree that out in the real world where things are engineered different terms are used.
For some weapons grade BS http://www.russandrews.com/images/pdf/GroundingArticleV3.pdf
Yes, inside studioland(tm) an audiophoolville(tm) they write about 'technical earth' (whatever it may mean on that day), but these experts are writing about something else.
Could you be more vague with your false allegations?
I don't perceive most people to be hostile, I perceive some them to be typical subjectivsts, which carries with it a lot of baggage, mostly composed of their being poorly informed about science, topped off with lots of denial and autosuggestion.
All by itself that doesn't make them bad people unless of course they have added being lying @-holes to their list of faults. They are usually just people that any reasonable, well-informed person should disagree with when their weirdness gets trotted out. Whether something gets said depends...
I have a more than a few friends in that boat, and while its not my preference, this is the real world and since there are people on both sides of any major issue, some of them have to be wrong.
I might be wrong about who to vote for in the next US election, in which case that sorta balances out my position on audio. ;-)
