jb Capacitors Superior Audio Capacitors Testimonials Summary

An old saying goes "No pains, No gains."  
In this year, jb Resource and Development department sacrificed lots of time and energy on designing your new product JSX.

In the process we encountered complicated engineering problems, once upon a time, we had an idea to give up.
But we are not. Perseverance and devotion make us success in the end. 
We consulted to some rich experienced audio capacitors designers and collected vast end user's using findings to upgrade and improve our JSX.

At the moment, we would like to invite you enjoy the most true testimonials about or JSX Superior Metallized Polypropylene Film Capacitors.
Believe it or not, you can try our JSX yourself and let us know how you comment about it.

jb Testimonial of JFX Premium and JSX Superior MKP Audio Cap

In the search of a affordable audio capacitors for decoupling purpose, I have got the JFX and JSX series from jb Capacitors. Now I will explain how they are compared with a a few others of similar size range.

Tested capacitors:
JSX: 2.2uF/250V
JFX: 2.2uF/400V
Mundorf Mcap 2.2uF/250V
Mundorf EVO 2.2uF/450V
Clarity Cao PX 2.2uF/250V

To have similar requirements I have a relay switch board next to my  pre-amp direct out from DAC. All DC coupled and no other capacitors in this way. DAC output impedance is 47Ohm, Pre-amp impedance is 470kOhm. These are very common values and should be give a good start point for comparisons. I can switch direct from capacitor to capacitor and DC coupled.

Mesurements are all very good. most below my measuring equipment. The tolerances where all below the printed 5%(JFX) and 3%(JSX). I have measured 1.36% and 0.99%.
The dielectric dissipation factor has been tan:<0.001 at 1kHz.

Listening test:
JSX: Clear, detailed, wide and open up presentation
JFX:  Detailed, gives a realistic soundstage and stress free listening. very natural and a good tonal balance. My favourite for acoustic instruments and voices.

Mcap:
Clear with more midrange. Makes sound a bit hard and grained.

EVO:  
Detailed and holographic presentation, seems to be a bit louder, but tonal balance is not perfect. After longer listening I feel like disrupted soundstage. 

Clarity Cap PX:
Musical and warm, but less detailed.

After burning in with 24hrs:
JFX: well balanced with more 3 dimensional stage, warm finish
JSX: clean and clear with rich details, but flatter sound stage
Overall both types are very high quality and for sure a good choice for a competitive price.

Summary:
jb Capacitors has surprised me with excellent capacitors. They are not expensive, small sized and good sounding. They beat most of even more expensive capacitors. Well done!

Best regards
Alex

jb JFS Motor Capacitors Should be Tested by Oscilloscope

Today we would like to share a piece of capacitance testing lesson with all of our jb customers.

Customer Sent: Thursday, July 09, 2015 6:48 PM
We received the capacitors from you and all cartons are ok, thank you.
First of all I want to thank you for the samples and gifts that you sent, I appreciate your kindness.
I checked all models of motor capacitors to see if they have the right capacity value.
The models between 10u and 80u have the right capacity, many models have 2-3% bigger capacity than rated, this is very good.
For example, 30uF has in fact 31uF.

The problem is with the models 100uF and 120uF.
100uF has in fact around 91uF; 120uF has in fact around 101uF

I would like to know why these models have such a low capacity.
I didn't expect to have such differences, I consider jb Capacitors to be a big factory with good quality.
It is important to know, I hope that next time we can find a solution to make these models with the rated capacity.

jb Capacitors Response: Thursday, July 13, 2015 12:45 PM
Before goods leaving our factory, we did all necessary electrical performance test & inspect, totally 3 times.
we made a JFS-15 100uF capacitor test with HF2618 instrument, a professional instrument for capacitance test.

Customer Sent: Thursday, July 16, 2015 5:48 PM
I am very glad to tell you that we tested the motor capacitors 100u and 120u with an oscilloscope that can also measure capacitance and the result is positive, the capacitors have indeed around 100u and 120u.
There is no problem to measure capacitors less than 100u with this general multimeter 9205, but for bigger capacitors we need indeed to use a professional instrument.
So I am glad that there is no problem with these capacitors from you. We are planning our next order very soon.http://www.jbcapacitors.com/
