WEET How Long Does Hi-Fi Audio Component Break-In (Burn-In) Different Ideas From Customers

WEE Technology Company Limited - WEE are Capacitors Specialist

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 WME 400V 6.8uF About How to Choose Tube MKP Capacitors Kondensotor For Crossover Audio Circuit

WEE Technology Company Limited - WEE are Capacitors Specialist

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 Small Music Capacitors With Big Powerful Enthusiastic Audio Capability

WEE Technology Company Limited - WEE are Capacitors Specialist

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.

WEET WME Premium Music Capacitor Cross Reference to jb Capacitors and Jantzen Audio Cross Cap

WEE Technology Company Limited - WEE are Capacitors Specialist

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.

WEET WME 1.5uF 400V Dispersion Factor (DF) Can Be Measured on LCR Low DF Audio Capacitors

WEE Technology Company Limited - WEE are Capacitors Specialist

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.

WEET Taiwan Factory is Focus for High End Audio Capacitors And Still Proivde OEM Service

WEE Technology Company Limited - WEE are Capacitors Specialist
WEET has two plant in producing audio capacitors. One is located in China Mainland for common products, another one is located in Taiwan for high end audio capacitors.

Most of our high end products are export to overseas market, but WEET brand is not quite well-known, the main reason is that we usually do OEM service for them.

From year 2020, we have different strategy, now we promote WEET capacitors all over the word. With same quality and better price, we have confidence that the success it not far away.

WEET Three Types of Audio Capacitors: Pure Aluminum Foil , Pure Copper Foil and Metallized film caps

WEE Technology Company Limited - WEE are Capacitors Specialist

Plastic film capacitors can be divided into two types according to the manufacturing process of their electrodes

WEET Film / foil capacitor
Metal foil film capacitor, a plastic layer of metal foil, usually aluminum foil, is directly added to the plastic film as the electrode; this process is relatively simple, and the electrode is easy to lead out, which can be used in high current occasions.

WEET Metallized film capacitor
Metallized film capacitor, through vacuum deposited process, directly forms a very thin metal surface on the surface of plastic film as an electrode; because the electrode thickness is very thin, it can be wound into a larger capacitance capacitor; but because of the thin electrode thickness, it is only suitable for small current occasions.
