Best electrolytic capacitors

Yep the vishay sounds better, it's not hard against a silmic (I really don't like the silmics though the one serie was usefull in serie as the SII with shiny and oscilating oaps at hidding things and matt and dark the sound (well sorry for the language shortcut, if I die it will be a scientist that drove on me with a 4x4)


I.e. a suit on a Vishay will alwats souds better than a naked Silmic II... the discussion turns on the disgusting side of audio porn ... I often laughed at people whom peeled of their 105°C caps in a smal rectifier circuitry for DACS or Pre...

............... I always use 1W resistors at least cos they sound better than lower wattage.

I see that we are fine-tuning the purpose of the OP, we have already gone from hearing exquisite differences in capacitors to hearing them in resistors due to the difference in wattage ...

I am assuming it is resistors in the signal path as I understand it to be the capacitors issue, although I may be wrong and that statement from what you hear refers to resistors anywhere in the circuit, it will always sound better 1 watt than 1/4 watts!

Extraordinary.

This is a fun thread. By the way, the company I'm working - a rather large producer of welding and solar inverters - is using exclusivley Rubycon in the high voltage parts. Doesn't say anything regarding audio, but we have 10years+ warranties. And that does say something about lifetime.
 
There is a reason those big polypropylene high voltage /mains voltage capacitors are cheap ---low quality polyprop. internally and yes I tried a few 20 years ago ( or more ) --then sawed them open to inspect them ---------.

What did you do with all that oil ?

I once opened a small axial MKV

We are talking the motor start type ---aren't we ?

I bought from Maplin (UK ) before young people stopped building electronics and went virtual helped with the removal of factories --helped to close down the business .

Very big issue with me in School teaching --social dogma -first-second-third --engineering ---"whats that --I have a screwdriver is that engineering" ?:)

Take up cooking young men for the service industry---er no thanks cant cook - can use a microwave though.

Thats a good point Diyiggy JLH recommended them and I used them .

But Polypropylene won out , I always use the "real deal"- NON metalised film types -dearer but worth it .

In scientific tests they come out quite good and for those of the subjective persuasion some think the sound "better " than polypropylene but I am talking non metalised .

Be cautious Tony, with these caps sound might cause you to wobble like the washing machine too :p:p:p
Joke aside I've been hearing good things about these MKV caps but never get to hear them first hand.

who? me? :D

i have used similar GE caps in a tube amp i made, 40ufd.....the owner was happy, and that is good enough for me...this is a D3a/2A3 single ended amp.

A few years back i experimented a bit with aircaps. Replacing pF riaa values between polystyrene, silver micas, kp, aircaps and home made teflons.

Results were rather startling but in the end could not really live with the aircaps. Perhaps the large size made them too vulnerable to rf noise. Or microphonics. At first glance they had an extreme "audiophile" character, speed, hf extension, jump factor. Sadly, in the longer term unlistenably bright and thin.
