Terry, tks for the invite. Whenever things get darker from changing standard caps to super-caps, we’re – to my experience – on the right track. It is closer to the SA in terms of sonic performance but at a price very similar to the PW range. Snappy and dynamic but rather up-front and forward in the midrange. To find out what we’re buying there’s really no alternative to simply un-wind the caps and see how they are made. After a very long burn-in time they did smooth a lot but they still maintained a sort of “hifi” sound. Putting a 0,01uF Vishay MKP parallel to them a good tweak for nearly any capacitor can create even more detail and separation! On top of this casting process, a ring of hard pressed paper strengthens the damping properties of the design helping music flow effortlessly”.
If you are using your M7 to drive a low impedance load, then perhaps you need larger value coupling caps. This is not meant in a negative way seeing the overall high quality sound level of this capacitor, as it’s character could prove usefull when fine-tuning a loudspeaker in a certain direction. More transparent than the slightly less expensive Superior Z-Cap, very detailed. Spatial information is above average in this price-range and it’s slightly warm presentation makes it ideal for long listening sessions. The Cornell Dubilier C is a well balanced souding capacitor in which nothing is exaggerated and that is a good thing. The amount of clarity that the Lefson produces is similar to that of the Mundorf Supreme EVO Silver Gold Oil but without the edge, therefore being more pleasent to the ear.

The Bennic Fiml has a slight nasal character and lacks detail. In direct comparison to a Mundorf Supreme EVO Silver Gold Oil they sound darker but that is only relative because the Mundorf focusses on the top end with to my ears a little too much energy.
I found the best combination was when it was used with soft dome tweeters, the leading edge of the capacitor mixing extremely nicely with the smooth character of soft domes. In just about every case there was an improvement in overall coherency and realism of tone.
The good PIO’s just have that density of tone and texture information; it may be at the expense of ultimate extension and definition at the frequency extremes, but for many, it may be a good trade. In direct comparison with a Clarity Cap ESA they are less up-front in the lower treble and have a better texturing of acoustic instruments like a violin for example.
Like most Mundorf capacitors, the Silver Gold Oil has a slight hint of top-end emphasis, this probably contributes to the perceived spatiality and micro-detailing. At this point, I am pretty much convinced that no capacitor can exactly sound like a PIO cap without actually being PIO, not even polypropylene in oil. Specially developed to meet the needs of the professional audio engineer in both hi-Fi and studio monitoring, these components are the result of extensive consultation between the audio industry and Clarity Cap.
Each lead is attached to the body of the capacitor with ultrasonic welding.

Speaking of smooth, AmpOhm is smoother than the Russian K40y, which in comparison can seem to have slightly more prominent grain-structure. The practically induction-free type of construction and the low loss factor of the MCap results in a very “quick” capacitor. High in contrast with a slight emphasis on the top end but always smooth souding. This way a blind test could be done completely without bias as to type, price, or brand. Very nice and coherent sounding with rich natural harmonics, all in all rather musical.
I am looking to replace the electrolytics in the preamp section of my amp with some film caps.
They could also be a handy upgrade for existing crossovers were space is limited because they are built more compact than regular axial capacitors, especially when you need large values. I have used the Mundorf Silver Supremes in several amps as coupling caps input, and between stagesand I get the same thing every time. The smooth top end gives a calm and natural presentation that is slightly on the dark side of neutral. They certainly weigh a ton due to the thick copper casing and feel extremely solid; they do not sound cheap, either.
Please read response here from people up-grading from standard PP caps to super-caps: That the K doesn’t have heaps of outlined detail at the top end can be quite usefull at times, for example, if your system is a bit on the hot side of neutral the K should bring everything nicely back into balance.

Maybe it’s easier to improve lower down the scale than further up it, I prsmium know, but that is how it cames across to me. Metallised polyester was certainly not the final word in this quest and metallised polypropylene became standard if we wanted something better.
Using the VDC Cornell Dubilier C as a bypass capacitor in the value 0,01uF really is the “icing on the cake” when you are looking for a low cost bypass capacitor that gell’s everything into one coherent sound.
I guess “tangible” is a good word to use to describe them. They take away the grainy edge from most capacitors.
They are plastic film caps and do not degrade with age. U r most welcome. However I think the soldering was fine.
The mid caps C3 20uf and the C5 uf are Solen caps coke can size. In most marketing material hold will read that super caps are made from two series-coupled, inter-wound capacitors, thus four times the normal size of a capacitor of same value as two e.
I actually have a few pieces lying around for a project I never got up and running. That’s probably why I define them as “analogue”. The line-up in no particular aluminumm Now the high is more pleasant; fuller and more enjoyable. The caveats mentioned are shared by basically all metalized poly caps to some degree and only noticeable in direct comparison to much more expensive caps; they shoud not dissuade users from trying out these overall transparent and airy caps, which are definitely one of the few affordable references out there.
Also there is cilm more convincing placing of the instruments in an orchestra. Furthermore, the only information I could find about these capacitors was from sites such as Ebay, Amazon and AliExpress. As hold caps this seems to be a consistent finding of mine.
Natural timbre with rich, although slightly rolled-off harmonic overtones. But I prefer the Cu-Sn on it’s own. The MCap forms the basis for vivid music reproduction rich in nuance.
Dynamics are nice and snappy and the treble is well detailed.
