In Reply to: RE: WIMA MP3-X2 safety cap firecracker. posted by Awe-d-o-file on November 04, 2014 at 19:37:33
Yep, you would think an experienced tweaker in Germany would know better.As for the WIMA MP3-X2 X2 AC power line noise filtering capacitor, I'm going to compare a WIMA MP3-X2 0.1uF 250V with the stock MKP type X-cap for a VansEvers Reference Model 12 Analog PLC. It's amazing how much sonic impact a very small value noise filter cap can make. I like the fact that the materials of the MP3-X2 involve more organic paper and resin. Al Sekela recommended the WIMA MP3-X2 as the only X2 cap he liked.
Do you have any experience of placing two conventional X2 caps in parallel like the unconventional Auricap Tweak?
TIA

I never did that tweak. It's two .47's from hot to neutral as I remember. They were rated at 630V but were not safety caps. They are also polarity marked but only for "best" performance and will work connected either way. I use Auricaps as an upgrade on the Detail Magnifier now. Safety caps supposedly have a construction that can handle line exposure and voltage spikes better. Either an X or Y type would do when going from hot to neutral.Al's parallel filter was more complex and has four R/C/R strings with different a cap and resistor values in each string. He also then made a version with a resistor/inductor string from neutral to safety ground.
Parallel filters don't suffer from the drawbacks of a series filter but have their weakness too like most things there are pluses and minuses. There's a schematic on my site and prebuilt boards in the trader here with the inductor string. Sorry if that's an ad just trying to give you the most info.

I understand the method, as I've implemented the Auricap Tweak (two non safety rated 0.47uF 630V Auricaps placed in parallel across L and N) for digital applications for a number of years without issue. My curiosity is about placing two safety rated X2 caps in parallel (such as two 0.1uF 250V WIMA MP3-X2) rather than only one cap as usual. Even though Audience implements Auricaps for their Adept Response PLCs, I feel far less confident using non safety rated Auricaps within a high current PLC than I do within a very low-current draw digital transport, and a very low-current draw digital interface processor.
I don't see any issue with doing it.
