Preamp Output Capacitor: Mundorf Supreme vs. Supreme Silver Oil

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.

That's amazing! Can't even imagine the differences after 100-300 hours of forming; the owner is going to be speechless...

Anyone compared the bass response of these two caps?

Yes. Both.  And, I was advised by a 50 year tech and a designer of my amplifier on two things.  The designer had to beat it into my head a few times for me to believe it.   I have the Mundorf SGOs in my MHDT Orchid DAC and the Mundorf Evo Supreme Silver Gold (non-oil) caps in my former tube amp. Guess which ones sounded fuller after 300+ hours of long and painful burn in.  The designer was right, he told me over and over to "go with the non-oil Evo Supremes" in my amp. He was right. It took a bit just to find the darn part numbers on the non-oil version. I swear those darn caps were still settling in after 400+ hours.  The 50 year tech warned me to "get ready for a roller coaster ride" with those caps for at least the first 3-4 months". Again, both were right.   

The new owner of the amp keeps calling and texting me to tell me how much better it sounds compared to the same amp with different caps, side by side. It kept improving beyond 400-500 hours.   Take it for what it's worth.  Mundorf needs to run in all their caps at the price they charge. Contemplating the roller coaster again on my new amps. 

Thanks everyone for all the cap comparison reports. Please keep them coming.. all are super useful. 

I just ordered a pair of Vcap odam caps to try in my preamp. Currently have some Mundorf m-cap supreme silvers. I’m tempted to try the bypass method with Vcap cutf’s after seeing what grannyring wrote.
