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.

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.
