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

I am also a big fan of the V-Caps.  I used them in the components I build.  I will be trying out the copper Duelands soon in my DAC so stay tuned.  Briefly tried the Jupiter but felt they were just OK but I never really let them burn in so take that into consideration.  Happy Listening.

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 ": 😊

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.

compare diameter/length/lead length for the same uF and voltage

The difference between Duelund CAST and Jupiter copper is this. I have used both in crossovers, tube amps, preamps, hybrid amps and dacs so I think I have had good experience with them both. You must let them break in for at least 150 hours to know how they really sound. This is a must. 

The CAST caps are a tad more tipped up in the upper mids. Some may like this as it sounds very resolving and open. For me this slightly tipped up upper mids caused my tinnitus to flare up. It was a tad too aggressive for me. I found this tendency when used in electronics, not in passive speaker crossovers. In crossovers they are magic. The Juputer caps have more top end air, improved Micro details, and an obvious improvement in bass impact. The Jupiter caps are far less expensive to boot. They seem to work better for coupling and output in tube amps and dacs. 

I have had  less experience with Vcaps, but one the one occasion I tried them they did not offer the "meat in the bones" weight and tone of the CAST or Jupiter caps. Crazy resolving however. 

Duelund’s Cast-PIO-Cu caps ARE more resolving and open, than any that I’ve tried over the years. I don’t want to hear anything but the original music and venue, without any editorializing. Duelunds are just less, "there" and allow me to hear further into whatever’s on my recording. I’ve had four in my Cary SLM-100 monoblocks, for a few years. btw: Some say that foil orientation doesn’t matter with stacked caps. Testing for noise proves otherwise.
