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)

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.
