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.

“...came along with the ODAM suggestion. They’re smaller and cheaper than the Miflex so I’m looking forward to trying them...”

Where do you find the ODAM capacitors selling cheaper than the Miflex?
A 0.47uF Miflex is around $25 vs. a 0.47 Vcap ODAM priced at $84. The price differential is a little less for larger uF values but definitely not cheaper. 
I’m very tempted to try the ODAMs in my Aric Audio Unlimited preamp already upgraded with the  Audyn True Copper capacitors. A clear improvement over the stock red Audyns.  Anyone has experience with the newer Audyn True Copper Max? For a 2.2uF value they are about the same price as the ODAMs.

I didn't know the prices of the lower values at the time of my post. I bought a pair of 2.2uF ODAM's from VHaudio for $175 and the cheapest I saw for Miflex was around $200 for a pair.
t_ramey, thanks. I’m also looking at 2.2uF values for my preamp and I now see the prices are on par for 630 volts rated model when buying a pair and ODAM pair is cheaper for the ones rated at 400 volts.
@kalali The Audyn True Copper Max are excellent caps. I recommend that you install the ODAM in a different component that can benefit from high quality caps. I bet that the True Copper and ODAM will provide excellent synergy. I use copper foil and ODAM caps in my system with great results.
