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

Two very experienced modifiers on this site Grannyring and salectric seen to prefer the Jupiter copper foil compared with the Mundorfs.

If price is not an issue then i would go with the jupiter copper foil.   That is comparing the Mundorf and Jupitor.  If space permits, i would get the Duelund cast hybrid.  

Thanks Charles.........I'll go in and check out the Junipers (copper)

Haven't yet tried the Duelund or Jupiter copper foils, but oh I so want to.

I would try Clarity CMR for the most neutral and high value.

I have issues with the fanciest Mundorf Supreme's. THey tend to scintillate, or hype up the mid to treble. It's not unpleasant, but to my ears far from neutral.

Mundorf MKP's are real steals and great for low level detail when you also need a noticeably dark cap.

Of course, check the physical sizes before you buy anything! :)

Best,

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.
