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.

My technician was able to install inside Don Sachs pré in addition to the Miflex 0.47 uF the Jupiter Copper Foil 2.2 uF for my Accuphase P-6100 which has 20 Kohms input. It is still early to definitive conclusions but the bass is certainly much more evident, fuller and more realistic timbre compared to Miflex, I believe that due to more correct capacitance. A larger capacitor would not be possible. In the future maybe bypass with the V-Cap CuTF or Duelund copper or silver (0.01 uF).
 could not afford the M Supremes. I am going with M SGO, white casing. 
Hopefully Richard Grey is doodling around his shop come monday morn. He is agaisnt swapping the stock caps for M's. 
We have like 20 caps to swap out on the Cayin Cd17 Mark1,,,,I'll posta   YT vid after the mod.

I went with these EVO OIl SGO...I attempted to read through and try to understand the dif twix all the caps offered by M, but really could not figure out why the Supremes were *so much superior* to all other offerings. 
The lower priced EVO SGO made my decision.
I am not buying into this *Supreme* thing with M. I think the added *Supreme* is ~~Snake-oil~ pun intended., as it is most likely the truth. Who can tell twixa  Supreme vs * regular* SGO??? 
make A/B testing, honestly , who could tell which set up has the S and which the *ordinary*???
As I say, hopefully Richard is round about his shop and will make the mod.
Will post a YT vid , ASAP

Hi @grannyring ,

Can you described a sound difference between:  Duelund Silver VS Sn-Cu bypass caps?

Alex
I wish we could rename this thread "Preamp Output Capacitor Discussion."  (or Comparison or Reviews) Super useful experiences and suggestions in here.  Thanks for the contributions.
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.
