When talking about top the audio and music plastic film capacitors factories, we will think about European brands, no doubt these companies put great money on trademark marketing.
However, as the labor cost in their domestic country is high, so they will find China factories to do OEM for them cost down. When they bring in the techniques, they also helped to upgrade the production ability of Chinese factories, the great beneficiary is Taiwan factories at first. Below are some examples for your reference. They do very good in audio capacitors.

Worldwide, Nichicon of Japan, Wima of Germany, ICEL of Italy and CDE of the United States are the top thin film capacitor manufacturers. Among them, Wima products are mainly used for high-quality audio, nichion is mainly used for electronic products, and CDE is a professional inverter film capacitor manufacturer. Others, such as Nissi in Japan, Philips in the Netherlands, and Kaili, Yudian and Huarong in Taiwan, are also world-famous film capacitor manufacturers. In terms of output, Matsushita Electric of Japan, EPCOS of Germany and KEMET of the United States are the world's leading film capacitor manufacturers.
At present, polyester film and polypropylene film are the main dielectric film materials for thin film capacitor in China. Polyester film is mainly used to produce DC capacitor, which is suitable for electronic products with high degree of electronic integration; polypropylene film is mainly used to produce AC capacitor, which is suitable for electronic, household appliances, communication and electric power containers.

Except for outer foil marking on the surface of the capacitors, some factories make their capacitors apparently have a shorter lead on the outer part of the foil. If I havent totally got this wrong it is suggested that the outer part of the foil should be connected to the negative side.
The outer foil end is connected to the lower impedance side, in a signal situation like inter stage/coupling this would mean the outer foil end is the input side (previous stage). In a decoupling situation the outer foil end goes to ground (lower impedance).
If you can not identify the outer foil of the capacitor by external appearance, and you also do not own an oscilloscope, we suggest you try below link and find other ways to identify film capacitors directions.

I've found it much easier to discern the orientation of the outer foil on film caps using TrueRTA spectrum analyzer software on my laptop. The most expensive version of this software (1/24 octave resolution) is only $100, lower resolution versions cost less.
I use the line in connection on the laptop with a simple cable consisting of a mini jack on one end and bare wires for signal and ground on the other, then watch the 60Hz peak on the spectrum analyzer go up or down depending on cap orientation. I also own a Tektronix 20 MHz scope and the TrueRTA method works much better for me.

How does Hi-Fi Audio Component Break-In (Burn-In)?
Do new capacitors in a crossover need breaking in?
Capacitor Burn In: correct method?
How long they need to full "burn in"?
Some feedback as below from different customers for your reference only.
Customer A: "Need" is a strong term, but to my ears, new capacitors do change in sound over the first 100 hours. The most noticeable to me listening to Daytons break in is around hours 20-30. I didn't believe it either until I heard it myself. For lack of a better explanation they get less "harsh" and "smooth" out. I'm not an electrochemical guy so I can't fathom the why on it.
Customer B: In my experience you’re going to have to let it run for about 6-7 years continuously in order for the capacitors to truly burn in all the way and sound their best. It’s also better if you use classical music to do so because of how dynamic it is, it will really make a major difference.
Customer C: Normaly capasitors need some time to "brake in" or "burn in". Usually it takes about 100-200 hours. Some of capasitors need more - for exampel Teflon caps need over 400 hours.
Capacitor burn in, how long does it really take?
Customer D: Absolute nonsense. If a cap required 50 hrs burn-in to perform correctly that would mean the mfg designed it that way and would include that information in the specs. Anybody seen any cap specs that state: "Requires 50 hours burn-in to reach full potential."? Me neither.

WEET Film capacitors – the best choice for music
Generally speaking, there are two types of film capacitors, film and foil MKP Capacitors, and metallized CBB film capacitors.
Electrodes in film and foil capacitors are separate sheets of metal foil wound with sheets of dielectric metallized material .These electrode sheets (or foils) extend alternately out of each end of the capacitor roll beyond the dielectric, which provide a large mass of metal material to which the leads are attached. Film and foil designs make the best choice for audio sound reproduction.
Metallized film capacitors greatly reduce the physical size of the capacitor. Discrete foil sheets are replaced with the thin layer of 99% pure aluminum or other metals that are vapor-deposited directly upon the dielectric material. Since the dielectric material is present at each end of the capacitor along with the metal electrode material, direct attachment of the leads are not possible.
The end-terminations of metallized film capacitors are created by the application of a fine, molten-metal spray. The spray makes contact with the layers of metal electrode resulting in plate contact. As the metal spray particles stack up against the aluminum electrodes, there is a compression bond resulting in a resistance higher than the discrete metal foils. The leads are attached to this metal spray, which adds additional resistance. This means there is a complex filter robbing the true, clear sound reproduction
WEET Film capacitors are widely used in audio circuits for a wide range of applications. For the optimum performance of a crossover network, film capacitors with low dielectric absorption and equivalent series resistance are commonly used. The characteristics of film capacitors make them the number one choice for audio applications. It is common for circuit designers to use a combination of different types of capacitors.

WEET is the earlest audio crossover factory in Taiwan, now we still keep some top products manufacturing in Taiwan as well, such as foil and film capacitors.
As this kinds of capacitors need very professional workers and advanced equipment, mostly we do OEM for European brands.
For general purpose audio application MKP capacitors, we are producing them in our China mainland factory, our China factory has been there for nearly 25 years, but without much popularity as we seldom look for customers, all the customers are introduced by each other. Now we think it is a right time to promote us to overseas market, WEET is fresh, but we believe with superior quality and competitive price, we will win in the end.
If you are looking for audio capacitors, please kindly send us your inquiry, free samples are on your request. We are ready to give your our best support.

When WEET WME compared to one of my favourite low-cost capacitors, the Mundorf EVO Oil, it is evident that the WEET WME still lacks some clarity and sound a bit forward.
The Mundorf EVO Oil emphasizes the top-end a fraction anyway, so maybe that comparison is not completely fair.
But on the otherhand it does explain on which side of neutral both capacitors stand regarding the amount of top end clarity.
What the EVO Oil does do much better is reproducing spatial information.
Comparing the WEET WME with other low cost types I would say that it comes closest to the Jantzen Audio Cross Cap or Jantzen Audio Standard Z-Cap.
Comparing them to the Obbligato aluminium-foil MKP there are similarities in that they are both a little upfront sounding when compared to higher grade types,
but at least the Obbligato aluminium-foil MKP shows a more open tonal balance. Like many of these basic quality MKP's WEET WME lacks some sophistication but their overall tonal balance is reasonably neutral.
The price / quality ratio is very good. I can highly recommend this capacitor if you are looking for a nice, but not too expensive MKP.

Whether DF value is high or low depends on temperature, capacity, Bai, voltage, frequency When the capacity is the same, the higher the withstand voltage, the lower the DF value. The higher the frequency, the higher the DF value and the higher the temperature. DF value is generally not marked on the capacitor, but it will be mentioned in the specification. DF can be measured on LCR. The dispersion factor (DF) is sometimes expressed by the loss angle tan.
The general DF value for WME series 0.001, so we remark a standard value on the datasheet specification table, but the real DF will change a little which depends on the capacitance, this is why we remark each DF for each item. However overall the DF is lower than 0.001, such as there are DF 0.0005 and DF 0.0008. As we all know for audio capacitors, the lower DF values, the better result. So WEET capacitors has actually lower DF values.
