Introduction of Mr. HF Choi
My name is HF Choi I am in the UK and looking for quality JSX cap for DIY hifi.  

Original letter from Mr. HF Choi
I received the capacitors a couple weeks ago and have installed them in my DAC.

I installed the 4 JSX 1uF caps as bypass on the output electrolytic caps of the DAC (2 caps per channel, each 150uF), so the bypass was less than 1%.
Immediately on first listen I could hear that the bass was bloated and the soundstage was closed in but the treble was a bit sweeter.

I let the DAC continue to play for 50 hours after which the bass improved dramatically.  It sounded like an extra octave lower was added.
Also, the treble was becoming more tangible and fine details throughout the frequency range became audible whereas before they were not.  
Nuances now audible in the music making instruments sound more real changed the tonality of entire pieces of music.
It slowed the music down somewhat for some fast bass music but also sped up music with fast transient treble.
Nice, as this probably means there's now less signal smearing and timing issues.

I find there's now a less of a difference between redbook tracks and DSD tracks.  
Both sound smooth and detailed now but DSD more dynamic with good recorded material.
Still very enjoyable with the improvement in tonality, timing, low level detail and nuances, and improved frequency extension - and of course price is very good. I’ve used them for hundreds of hours so far.

I chose the JSX because of the small size. Compared with large and expensive Mundorf and similar grade caps, it is an easy choice. Very high price/performace ratio with the JSX.
I am very satisfied with the performance of the JSX . Thanks for a great product!

When talking about motor capacitors, the first idea come into your mind is some overseas brand, such as Epcos, AVX and Kemet.  
HongKong brand " jb "  also offers a wide range of products for motor start and run applications in plastic and aluminum cans.  
JFS - 6 is one of the most popular items in our production line.

Application:
The capacitors described in the current catalogue are specifically designed for the start and the run of single-phase electric motors. 
Usually the capacitor is connected in series to an inductive winding into an auxiliary circuit for a single-phase motor or in parallel  phase/phase into three-phase motors when powered by a single-phase circuit.

Safety Class:
The degreee of safety is marked on the capacitor according to the following symbols:
(P2) the capacitor has been designed to fail only in case of circuit cut-off and it is protected against fire and electrocution risk.
(P1) the capacitor can fail either by a circuit cut-off or by a short-circuit and it is protected against fire and electrocution risk.
(P0) in case of failure, the capacitor does not have any particular protection.

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.
