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

Rodman,
It's interesting to note that when proponents of the VCap describe its character the word is neutral. 
Duelund CAST proponents descriptive word is natural.  Both are meant to be complimentary yet they convey perceptive differences. Having used both capacitors I understand the chosen terms. Natural is the highest compliment I can use to describe an audio product.

Hi Bigkidz, 
Impossible to predict if you'll prefer the Duelund CAST vs VCAP, too many variables involved.  I do have a favorable bias toward the Copper CAST,  I just find them sublime "in my system ": 😊

I can’t disagree with salectric’s point, it boils down to personal preferences and that will never change. I haven’t used the V Cap copper but have experience with their Teflon tin foil  and OIMP capacitors. We all simply hear what we hear. I could see where someone would categorize the Teflon V Cap as more ideally neutral and a preferred choice depending on the particular component, system character and objectives.

Jupiter and Duelund CAST are beautifully "natural"/organic in character/tone and this is what I find most important and desirable. It depends on what a listener prioritizes, no right or wrong. There’s a capacitor available that will suit a given taste once one determines what specific sound they’re seeking. Plenty of good choices.

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

I placed Jupiter copper foil caps in my 300b SET (replacing the stock Solens) and it's a worthwhile upgrade.  I went with them rather than the Duelund CAST due to the lower cost and enthusiastic recommendations. 

The Duelund CAST is superb in my DAC  and speaker  crossover (tweeter).  Though expensive I believe they are definitely worth their cost.
