jb Capacitors Audio Capacitors JFX User Feedback Sharing

Welcome to try jb Capacitors and let us know your thinking about the product. Here we would like to share a feedback of jb Audio Capacitors JFX from the user with jb customers. We want you can get more information of it from this sharing.

Quote" Have you guys tried the jb JFX caps yet? Excellent and super cheap. Pretty sweet sounding. Several of the guys on the Audiogon thread use the copper cast Duelands and think these things are really good. They are not marked for outside foil so you will need to test and mark each one. Chinese caps for everyone!!!! So, we may have a new World's best cap coming."

http://www.head-fi.org/t/284863/orgy-of-capacitors-the-cap-thread/360

Quote" Interestingly I also found out that Mundorf approached them to manufacture the JFX as OEM part for them so they could create a new premium brand to sell under the Mundorf branding. jb decided not to pursue this as it did not add value to their own brand which they want to promote with the JFX. The JFX caps display signs of a near perfect capacitor. +Total harmonic and IMD distortion and phase distortion are virtually immeasurable, while all losses are near zero in every aspect. jb JFX caps will allow your music to be accurate and uncolored in every way. Initial observations they seem well made no obvious flaws they arrived quickly, well packaged.

Quote" Whilst searching the web, I came across jb Capacitors, a Chinese manufacturer, I ordered a couple of their Premium capacitors and they arrive swiftly within a couple of weeks from China. 

After installing them I did notice an increase in clarity and treble response over the Blackgates that were previously installed. Overall very pleased with these capacitors and will not be going back to reinstalling the Blackgates."

Your feedback and advice will be highly valued. We will try our best to provide the best service and quality. We are sure jb Capacitors Company is your trusted choice.

jb JFX and JSX Audio Capacitors are Non Polarised Type

Sometimes, customer will be confused by the so-called "outer foil" or the "inner foil"of our audio capacitors.
Today we would like to tell you more about this point. I am sure you will understand by below customers explanation.

" I have all my JFX caps soldered in at the moment, but plan to try some Jensen caps in place o them, so i will try to do the test as well. 
With a sensitive millivolt AC meter i think you could see the difference just by connecting it one way and touching the cap. 

The induced mains hum will be higher when the outermost foil is connected to the anode of the meter(maybe).

I think more and more that this is an example of "audiophile", which means that people searcing for better and better sound, and not always exactly knowing the technical aspects of it, they will assume one way is better because another cap manufacturer said so.

I feel that the JFX is a solid performer in either direction used(after all it is a bipolar cap as you stated), and i feel that the price/performance ratio is excellent."

jb Best Audio Capacitors JSX and JFX Test Review

Dear Sir or Madam, 

We are very glad to announce an encouraging news to all of our jb Capacitors customers that our JSX and JSX get high compliment from a senior audio specialist.

Under recommendation of one of our French customer, we know Mr Tony Gee since year 2014, Mr Tony is very generous in helping us, not only for testing the capacitors , but also in sharing some technology expertise.

Hope below valuable original comment can help our customer in choosing a right audio capacitor.
"Here are my results after several months of listening to the capacitors:" 
--- From Mr Tony Gee  http://www.humblehomemadehifi.com/Cap.html

jb CAPACITORS JFX PREMIUM (black type)
www.jbcapacitors.com/Plastic-Film-Capacitors/JFX-Premium-Metallized-Polypropylene-Film-Capacitors-Axial.html

The jb Capacitors JFX Premium sounds quite organised when compared with other standard MKP's in this price range. Like all basic MKP's thay can get a bit muddled when complex progamme material is fed to them but they do have a certain tidyness to them which makes them go further before that sets in. The JFX Premium is reasonably well balanced and neutral and in a positive way nothing sticks out. If you are looking for a basic MKP at a very fair price then the jb Capacitors JFX Premium is a good contender.

jb CAPACITORS JSX SUPERIOR (white type)
www.jbcapacitors.com/Plastic-Film-Capacitors/JSX-Superior-Metallized-Polypropylene-Film-Capacitors-Axial.html

The jb Capacitors JSX Superior is similar in character to the old black JSX type but now has added clarity making them a little more open sounding. This works especially well on recordings of jazz-trio's or other small ensembles making it easier to pick out the details. The Clarity Cap SA and ESA will give you more image depth and richer harmonic overtones and the Mundorf EVO Oil will give you sharper leading edges to notes but it must be stated that those capacitors are in a higher price bracket. It is just to give you an idea in what sound quality range we are looking at here. Personally I actually prefer the JFX Premium in being a tad more expressive and coherent but I could imagine the JSX Superior to work well if you are looking for a more clean presentation.
