I believe you still remember this one? I think it’s time to give a short review of it.
As comparison, I will use Jensen 4-Pole capacitor as both has same capacitance (470 uF).
Caveat: The Jensen 4-Pole has been used for quite some time as it’s my reference electrolytic capacitor. While this new ‘No Name’ capacitor is currently fresh from the oven. Quite unfair for the comparison, but from my experience, the ‘talent’ of capacitor should easily leave an impression on first sight, I mean, first listening test 😉
So, what is my first impression?
This new ‘No Name’ capacitor has more ‘analogue’ sound. The vocal is sweet enough for an electrolytic capacitor, but not too sweet. The resolution also clearly ahead of the Jensen 4-Pole. The staging, depth and width, also much better than the Jensen 4-Pole (quite obvious on 月光å°å¤œæ›² by Cai Qin). Dynamic and headroom also not limited. Quite interesting. It just has more timbre and more ‘sweet’ harmonic along the music. Norah Jones, Cai Qin, and Livingston Taylor easily on this ‘No Name’ capacitor side. So, I can easily say this is more musical than the Jensen 4-Pole. The different is easily recognized on several seconds after the music played.
Am I saying this new ‘No Name’ capacitor has no weakness? Not really.
The speed is a little bit slow. This is quite obvious when playing ‘Black Magic Woman’ from Patricia Barber. During the last 3-4 minutes to the end of the track, we can hear and test the speed of the system (best part of the track actually). I can say this ‘No Name’ capacitor has the dynamic, power, and everything (including the guitar distortion which I prefer this capacitor instead of the Jensen 4-Pole). But it just seems like to play the music easily and constant speed (which eventually translated into a bit slower, especially when compared to Jensen 4-Pole). I could say it lacks (a bit) of pace?
Despite the speed, it has everything to make me fall-in-love at first listening test (my fall-in-love at first sight should be my wife;). Tonality wise, it’s musical. Staging wise, it’s deep and wide. Harmonically wise, it’s rich. Resolution wise, I don’t think we can have a lot of electrolytic could outperform this one. Male and female vocal? For me, it’s no contest against the Jensen 4-Pole.
The pace reminds me of too much Kiwame resistor. But Kiwame will hide the detail and resolution, while this new ‘No Name’ capacitor will keep the detail and resolution there, plus all the timbre and harmonic.
Will see how this will perform in next several hundreds hours. With additional extra of speed, this would be perfect!
Or, maybe it will need some extra tuning 😉

Tidak lah bro, ini pesan khusus koq dengan spec/design saya.
Thanks.

Yang ga dateng ga usah komen lah 😉
Thanks.

March 18, 2013 22:51Try it in the circuit with shorter leads . this should reduce the inductance of the wire and give a bit more speed. What might the cost of the Jimmy’s kelvinated Supper Cap ?

March 19, 2013 10:09Hi Thom,
I’m working for another prototype to see if I can catch up some improvement.
Meanwhile, giving some time to break-in the capacitor would be a good idea.
Currently, longer leads are useful to give flexibility when testing it on different circuit – I realize that would be some quality risks for having such long ‘antenna’ leads like this.
The final production (if ever exist) should have short 12 AWG solid wire.
No information about the pricing, yet.
Thanks.

March 19, 2013 10:13Hi Jimmy,
are you planning to sell this super caps? please let me know the price and shipping to canada. i can have a use to replace my 4poles capacitor. seems it would be a dramatic improvement for me. thanks mate for nice website. cheers, Bob.

March 19, 2013 10:15Bob,
As I mentioned to Thom earlier, I haven’t seen any price at present time, nor the possibility of production of this caps.
But will see. Time will tell 😉
Thanks for your interest.

April 8, 2013 00:45well, If you do not intend to make this a Commercial producet, than giving advise how to build would be great….
Best Regards

April 9, 2013 09:10Hi Frank,
If the quality is good (it would need several testing phases), perhaps I would make this as commercial one 😉
Thanks.
