The best coupling caps in power amp ?? Mundorf, Infinicap ??

Do your homework, as you’ll find that one or two expensive "boutique" caps mentioned are very likely just re-branded Solens (which are far cheaper) compare diameter/length/lead length for the same uF and voltage and you will see why.

If you know which boutique company just re brands Solen caps, why not name them?

Like I said do your homework, it’s not that hard they all have spec sheets.
The mods would have a field day, with me being a manufacturer if I named someone.
Look it up for yourself, then you to will think twice, paying ten times more for the same cap.
