Preamp Output Capacitor: Mundorf Supreme vs. Supreme Silver Oil


Anyone compared the bass response of these two caps?  I bought the Supremes for trial purposes and really loved what they did to my system's imaging (front to back layering) and immediately bought the Silver Gold Oil Supremes.  Unfortunately while they were smoother, more beautiful, and even better at imaging, they had no bass (actually, they lost bass as they broke in).  Anyone know how the Silver Oil's fit into the line?  

I'm using them in a Don Sach's DS2 Preamp ( https://systems.audiogon.com/systems/7983).  

Thanks.

Those Duelund tinned copper caps are so special. If you can afford those, they will easily surpass the Mundorf caps in every sonic area. I think you suspect that is true.  They are pricy! 
They are easily the finest sounding cap I have ever used and I have used most of them 🤪 They are as you say so natural and real sounding.   
I have used and continue to use the Duelund silver and Sn-Cu bypass caps. Both are great. I find the Sn-cu, like the main Sn-Cu cap, are the best caps out there. They are simply beautiful sounding with all the detail and openness one could ever want, but served up in a natural and unforced manner. They also have great body and weight which is my only knock of Teflon caps which can sound colder and a tad leaner. 

The Vcaps have a sound as all caps do. I am also trying the combo of ODAMs bypassed with Vcap CuTF. I don’t expect them to sound as good as the Duelund Sn-Cu, but we will see. I am sure this combo will deliver clarity in spades, but will that have that wonderful tone and beauty of the Duelund Sn-Cu? I have my doubts.
Wig. They are said to perform even better, great results, with a .01uf Vcap CuTF as a parallel/bypass cap. That is how I am using them.  
I have an update. I just completed an MHDT Orchid upgrade for a customer with the Vcap Odam & Bypass CuTF on the outputs. The unit has about 7 hours on it. Keep in mind I also upgraded 10 resistors to Vishay ZFoils and Audio Note Tantalum.

To say I am pleased is an understatement. The unit is more open and vivid sounding with a larger stage and far more bass impact. Details once missed are now revealing themselves. Realism is improved. All with a silky smoothness and meaty warmth that is a must! Still early, but so far so very good.
Yes, do bypass with the CuTF Vcaps! Chris of Vcap shared with me this gem.   The result is very good.  .01 uf.  
Yes please check them out.  Bypass with the Vcap CuTF.  My favorite cap is still the Duelund CAST tinned copper foil.  However, they are just crazy expensive for general use. 
Amen! Bypass with CuTF .01uf from Vcap and try to contain yourself after some 60 hours. 
Hi Alex.  Cannot say for sure as I did not do a side by side, cap to cap direct comparison.  I was lucky enough to compare both as bypass caps with a .47uf Jupiter copper foil in the same piece of gear.  The Sn-Cu has more of that special musicality and perfect tone. It just sounded a tad more real, natural and spacious.  The silvers were also beautiful, but just not quite as natural or real sounding in this one piece of gear.  
I have upgraded several MHDT Orchid dacs with the Vcap Odam caps in combo with the Vcap Cutf bypass and the results are stellar! 

The bass energy is the best I have heard from any cap...period.  Wonderful.  In addition, the mids and highs sound is so vivid and full. They are fast becoming my new favorite cap combo. I love how these caps deliver vivid detail and realism with a warm and rich beauty that is so pleasing and alluring.


Depends what you are looking for. The Odam & CuTF combo from Vcap will be more open, vibrant, dynamic, resolving, 3D and far better bass. The copper foils from Jupiter, Miflex, Auydn and others will give you more rounded warmth.  They are a tad darker. 

I am a big Jupiter copper foil cap fan, but the Vcap combo is just better sounding to me in the ways I mentioned above. They also deliver the goods with nice warmth and richness. 



It depends on the combo and position. The Vcap Odam & Cuft bypass are a match in heaven. Chris from Vcap turned me onto it. I will say it is magic on the output of a dac which is where I have used them on 5 occasions now. I am sure they would sound as wonderful together on the output of a preamp.  I am using them on a tweeter next and will report back. 

Some combos just work and some just dont.  Learn from experience.  The Jupiter copper foils bypassed with the Duelund silver foil bypass cap also works wonderfully.  In my experience the two examples work and I have used them extensively. 
Sorry. I can’t explain as I am more of a experiential sort of guy. I try and enjoy or not. I will add that it’s all about the synergy between the stock piece of gear and the cap you are thinking of adding. For example the stock MHDT Orchid dac is warm, rounded so more air and vividness is a synergistic plus. The trick is not to go to far and lose the stock unit’s wonderful weight, bloom and body. That’s why I would not use a Mundorf SGO alone or with a bypass of any sort. However, the Odam & Cuft combo works perfectly for top to bottom correctness of tone.....perfectly balanced.   One has to know the sonic personality of the parts being used as they do indeed have a sound.
All I can say is it sounds better in my highly resolving system. It just does. Experience and try for yourself.  This is the only way to know for you .
