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:"

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.

jb Why You Use Capacitor in Transistor Amplifier Circuit?

Keywords: Ripple Voltage, AC power supplies, audio amplifier, open-loop

Capacitors are used to couple each stage of an amplifier to the next, to help remove ripple voltages from rectified AC power supplies and they are also used to tune circuits to get the required frequency response, such as a tone control in an audio amplifier, or an RF or IF amplifier in a radio receiver front-end.

Capacitors are also used to bypass emitter resistors to improve the voltage swing and lower the AC output impedance of class A amplifier stages, and also used in negative feedback loops to stabilize an amplifier's open-loop gain.

We jb capacitors company professional produce MKT & MKP film capacitors, total 22 series. we have two representitive types used in Amplifier, audio, sound system. please check below.
