    Default What are the very best caps for the PSU?

    I'm in the middle of completely over hauling my Sondex 100 amp. Currently I'm looking at replacing the four large caps in the power supply.

    The four large black caps appear to be an unnamed UK brand, I've not removed them yet but these are the ones I'd like to replace.

    I've been looking over at HiFi Collective and have short listed several brands mainly :-

    Audio Note, Axial, BHC, ClarityCap, Cornell Dubilier, Evox, F&T Electrolytic, Jensen, LCR Mundorf, Nichicon

    I'm not restricting myself any of the above brands. I can't see myself wanting to sell the Sondex Amp and I'm prepared to invest heavily in the amp as I think it's my last port of call in Valve amplifiers.

    So my question is quite simple what do you consider the very best cap replacement for PSU duties?

    Hi Andrew
    I use and can recommend the Nichicon Gold Tune, great caps and very reasonably priced.
    I used them in both my dcb1 builds and will be using them on my next project.

    Merry Christmas....

    Thanks, Mundorf has also been suggested.

    The best in terms of long life with decent sound are the Kemet ones available from RS and others. Nichicon gold tune are decent but not available in high voltages

    Can’t say I’ve heard a great deal of difference with PS caps, so I’d just go with something of decent quality that’s fit for purpose. I’ve used Mundorfs before and been happy with them.

    Ali, thanks. I didn't really think about the effects of the caps on the sound.

    The amp is stuffed full of RS components. Nichicon are also on the short list. Thanks David, longevity is always an important factor.

    Yet another recommendation . Thanks.

    When starting this thread I assumed that there may have one/two caps which would have stood out as being regularly used. I'm now learning that different people use caps for different reasons. Some for a financial view point, other to "voice" an amp etc. I'm primarily interested in using the best quality components for the best performance from the amp. I'm happy to pay good money for top quality components but I'm not willing to pay silly money for caps i.e. some of the duelund stuff. I think it may be more beneficial to research the properties of the caps and maybe see if this can help me decide.

    Personal choice is Audio Note Kaisei.

    Made a marked improvement to the Krell. Really well made and even though they aren't cheap, they arent ridiculously priced.

    I hope to redo my phonostage and the Krell with them, in time.

    The ANs are Rubycons. Should be good.

    Yeah could be a good choice. A few people I know used to swear by WKZ’s but they’re unobtainium now so these might be a good alternative.
