Mundorf RXF MKP 600VDC – 3% tolerance

Mundorf RXF MKP 600VDC – 3% tolerance

Technical Specifications (according to manufacturer): “Optimised Winding Geometry. Extremely short low-loss signal transmission. Maximised internal contact surfaces. Extremely reduced residual-resistance (ESR). Considerable low residual-inductivity (ESL). Sealed foil coil against microphony effects. Polypropylene capacitor-foil, alu metallized. Massive connector plate”.

Sound: Compared to the M-Cap they are cleaner and more transparent. The M-Cap's are slightly more midrange focussed. The RXF are nicely detailed without being "edgy" but could be a little smoother sometimes, they tend to draw your attention to the top-end more than the rest. This top-end focus does gather points regarding the retrieval of ambient information and reverberation. But I find the lower treble lacks some refinement, a bit "in your face". They do get better over time but a slight "glare" stays. The Supreme is similar in spatial information but more refined and therefore better. I also find the Clarity Cap PX to be smoother, rounder and therefore scores better in long term listening. This is most evident on well-recorded classical music. Overall I am still very positive about the RXF (especially considering the price) and see them as a welcome arrival for the budget sensitive user. They could also be a handy upgrade for existing crossovers were space is limited because they are built more compact than regular tube-shaped capacitors, especially when you need large values.

Verdict: 8
