Anyone has experienced with different electrolytic caps in a Jung superregulator, to see if there were any audible differences?
It's one of the best regulators around, so there might be different results with some caps.

True. For small quantity, the Sanyo are still available on eBay. I really liked the very old "SG" series with purple sleeve and gold-plated leads.
Gentlemen, can you provide a technical reference to support your respective argument? Any technical publication, not video, will be much appreciated.
I have bought the Jung regulators on eBay. I am going to use them for buffers, at the input for my Holton 1200 Mono. I bought 8 so I hope they are good. Maybe I will change the capacitors later.
Oddly enough this was just discussed on the super regulator thread:
Super Regulator
Evidently, while most of the circuit component choices were carefully researched and chosen the electrolytics were not.
The 120uFs were used because they were handy and worked. Jan has used 100uF and they worked.
Additionally the specs of these caps are evidently not critical except for the output caps: they should not be a high quality, low ESR type.
Please let us know what you find and use successfully... and what doesn't.

Datasheets for capacitors are not a secret. Solyd polymer caps have almoust an order larger ripple current capability so they are very suitable for SMPS output circuits (high frequency dc/dc convertors).

If you go to a website like RS Components they have PDF download data sheets on solid polymer caps.A lot of the latest PCs for instance use these caps as substitutes for MLCC bypass caps to save space because of their high ripple current ratings and high speed which standard electrolytics cannot achieve.
As substitutes for MLCCs (MultiLayer Ceramic Capacitors)? Are you sure about that?
From my recollection, you mainly find these in the CPU and GPU VRM sections, where integrated powerstages (for example IR3553, I think that is an older one) are controlled by multichannel PWM controllers to get 1.2ish volts and lots of amps from 12V rails.

I mean they could supplement them, maybe you need less MLCCs, but substitute? I am not so sure about that, but maybe I need to do some research into that claim.

See "Frequency correction factor for ripple current".
Ripple current ratings of polymer caps are generally much reduced in lower frequency.
Only 5% in 120Hz from rated ripple current!
Polymer caps are not suitable for rectifier reservoir capacitor.
But it does not applicable in downstream of regulator (You should take care of reglator oscillating).
Thats true but the application say for a output buffer of a DAC of 2volts max output requires very little current.Even driving a 10kohm passive preamp at this voltage only requires 0.2 milliamps.
Anybody ever tried the DNM 10,000uf 4pole slit foil reservoir caps made by BHC and Supertech.
I use these in my poweramps and find them superior to any other cap I`ve tried, second only to the 10,000uf Blackgates which I also use as a bypass on the outputs of the 4poles!

Which are the best choice now in 15000uF screw terminals caps?
Those expensive ones, very good ones, that Epcos made are not made anymore. What would be a good alternative?

Vishay makes some that appear to be comparable to the B41550, but I haven’t tried them.
I went with a set of used Epcos that are working fine for a recent amp build.

Analog-sa,The 4pole DNM caps I noticed recently have a revised wiring regime.
Originaly the centre tap inputs and outputs were separated but now it is suggested that they be linked together.After doing this rewiring I found the sound quality slightly better,not subtle at all.How are yours wired?
I do not actually agree with this statement across the board. The Silmic caps present a coloration to the audio signal whether they are used as a power supply filter cap or a DC signal blocking cap. In both instances, they provide a tube like sound coloration. They also, in a way, slow down the attack on the waveforms. I stopped using the Silmics a long time ago and just recently replaced some Silmic DC signal caps with the Nichicon MUSE bipolar. The MUSE were much more transparent and uncolored.
Those who love the Silmics will love them for their sound. Others will not like these caps at all.
How would you say compare DNM or BHC slit foil capacitors with Epcos Sikorel capacitors, which I believe are not made anymore?
