WEE Technology Company Limites On September 24, 2026

The customer was interested in the WME film capacitor and wanted to evaluate its performance through actual testing.

After receiving the samples, the customer carried out testing to check whether the capacitor met the required specifications and performance expectations. 

2. Customer Feedback

"I immediately tested the capacitors, and all I can say is "Amazing."

To my ears, they match my audio system much better than world-famous brands like Solen or Audyn.

Compared to Solen, the sound is smoother and richer, yet not muffled at all. The high-frequency extension is excellent and feels very good.”

Our customer from Malaysia purchased WEET WMG Aluminum Foil and Film Capacitor for coupling function in guitar amplifiers.

2. Product Testing

• WMG 0.022uF 630V ±5% OD*L8*24mm Axial RoHS 

• WMG 0.047uF 630V ±5% OD*L12*24mm Axial RoHS 

• WMG 0.1uF 630V ±5% OD*L12*30.5mm Axial RoHS

3. Customer Feedback

"Very clear/detailed, a bit warm, but not as woolier/vintage sounding as polyester, as expected.

The less hi fi sound is preferred for guitar amps, usually.

But this is to be expected, and your caps perform quite well against what we currently use.

Perhaps, with more burn in, the performance will shine better.

I will also test your other caps."

--Nik from Malaysia

4. Conclusion

WEET WMG Aluminum Foil and Film Capacitors are constructed using separate layers of premium foil and polypropylene films, rather than the vapor deposited metallized film used by most other manufacturers.

WEE Technolgy Company Limited Published On Sept 11, 2026

Our customer from Germany recently purchased WEET WMH Audio Capacitors to replace the original capacitors in the speaker crossover of the Claro 6.2 by Sonor Audio.

2. Product Testing

Product Testing:

• 10.0uF 100V +/-3% 28x85mm Axial RoHS

• 4.7uF 100V +/-3% 21x75mm Axial RoHS

• 2.2uF 100V +/-3% 17x58mm Axial RoHS

3. Customer Feedback

"So (once more!) it was a good thing to replace all the caps with your WMHs, but they need a run in time of about a week. That is an absolute must!

By the way we also measured the usual specs of the Caps, ESR, Dissipation Factor, tangent delta, Q factor ….

All values of the WMHs were clearly better than in the Caps of Sonor Audio.

So there is no doubt that your caps are a lot better regarding measurements and sound quality as well.

We only can recommend speaker owners to change to your capacitors before any considerations of new speakers!"

--Hubert From Germany
