I thought traditional testing uses the eyes to override and bias what the ears think they hear? Hence silver cables sound 'bright' while copper sounds 'dull'. Expensive capacitors sound better than cheaper capacitors, even when the correct value is used as a coupling cap. Bypassed capacitors sound better, even though the bypass may introduce a resonance and thus extra phase shift.
Actually, when I was at the ChengDu audio show in China, I asked one exhibitor whom I know whether we would allow me to replace his interconnects with mine, we listened, and another listener said the interconnect sounded like it had some silver content, which was correct, I would not have thought it could be noticed, but that was detected because the person was really experienced.

What is right is the eyes are their logic ! Like the price of two caps related to the value !
0.1 uF costs xx while 10 uF costs 10 * xx or even more : there is no industrial logic behind that ! It's like if the low values were solded like spices : salt, Pepper and the biggest like some meat ! It's disgusting to sell caps values like if it was like kilos and caviar ! Same logic than with cosmetics and jewels !

No. Except to those who trust machines more than their ears. Which is what electrical measurements rely on. But that "tradition" is no such thing; traditional testing is done with ears, and for obvious reasons.
Most consumers think in linear terms when it comes to pricing of products. However, smart companies price to perceived value. So, when audiofools buy a cap that's priced 10X higher than another, they think the sound will be roughly 10X better. Sadly, many listening studies have shown that to not be the case.
So Eldam is quite correct correct IMO citing cosmetics and jewels as an analogy.
People can easily agree on a relatively uniform set of test data, rather than a bunch of anecdotal opinions scattered all over the place like we have here with bypass caps performance re. value, brand, voltage, mateials, etc. etc.etc....
I rely on cross reference of listening and measurement. Both are equally important to me.

I would say "Greedy" companies price to perceived value.
Horourable companies price to return an acceptable profit.
Quite. But that doesn't mean they are right. It's human nature to take the easier approach, especially if you are validated by others agreeing with you.
In the case of Toole, et al, they were right with the correlations they found between listening panels and their test data. So, that data established a basis for a "guide" in judging a speaker just by it's FR tests....and it's only a guide which is better that no guide, IMO.
A lot of cost goes into amortization of development effort. But pricing strategy is also important. For example, there are lots of people whom find iPhones high priced, I look into lots of functionality and performance issue which integrate with what I do. So the latest and created may not be the best for me, but I ended up finding value in the Apple product line, including second hand. Same with capacitors. I like the performance of really good capacitors, but sometimes the form factor or price is not going to fit my target budget. This is when I need to start looking for alternatives to obtain the best for a budget. This is not easy. But again, I can do this because I really do not factor in development amortization. But most companies have to consider this. I have done this kind of analysis, and I assure you paying someone to do development for performance breakthrough is not cheap.

A company would logically be wise to offer a great product at a reasonable price, then follow on with additional products, maintaining volume, keeping prices the same but reducing costs, increasing profits...
Easier said than done.
My go to extreme capacitor for coupling has been the Russian K71 polystyrene, but the prices have gone up a bit, with fewer values available. The times I have used these they have been just a wee bit thin in the bass department. However these may be one of the best bargains in a highly detailed capacitor.
I noticed that the Claritycap(MR)had a rash of marketing in the way of enthusiastic consumers a few years back. In the wake of that, there hasn't been as much recently, and the remaining stock has been discounted some 50%. People love something new, human nature I suppose.
There are just so many combinations of parts possible, is part of what makes it such a fun and interesting hobby.

Sorry to hijack... but this related.
I have a blown cap in my PSB 1000 crossover board... it is 15 microF, 100V, NP+-10%. Not sure what NP means.
I bought 2 caps from digikey:
100SXE15M Panasonic Electronic Components | Capacitors | DigiKey
UKL1H150KEDANA Nichicon | Capacitors | DigiKey
Which one do i use??? Neither??
I don't THINK my 130W/ch Denon avr4310 will pump more than 50V through it... so the cheap cap has a tighter tolerance and is the better choice? Orrr, the more expensive unit is better for reasons beyond my understanding?
Thx!

NP is intended to mean Non-Polar, but it is actually Bi-Polar.
All electrolytics are polarised. The Bi-polar type are polarised for both directions of current flow. They cannot be converted to Non-Polar.

I specifically asked a Capxon agent what the difference between NP and BP devices are, the answered I got was NP has a lower current rating than BP devices.
Some plastics are non polar.
A few plastics are polar, but to a very low extent.
This is one of the differences between MKP and MKT/S

Hi,
With the electrolytic bi-polar as the green Muse ES (Nichicon), I see there is a longer lead for the positive pole I assume.
Does it mean they can be used at reservoir caps or behind a rectifier in shunt position to the pcb gnd ? Does the sense is important as they are bi-directional or should they be avoided at such use ?
