Another great capacitor shootout:

Here are the comments on the Mundorf Supreme Silver Oil:
Mundorf Supreme Silver / Oil
What a breath of fresh air ! Coming from the M-Cap, the Mundorf Supreme Silver in Oil is a treat for the ears. The Mundorf Supreme family of capacitors have a distinct family sound. The Silver in Oil is much more liquid and open compared to the Supreme. I actually prefer this to the Silver / Gold. The Silver in Oil is very extended at both ends with excellent microdetails in the midrange and high frequencies. It is also exquisitely refined with an excellent balance struck between being analytical and musical. It lacks the midrange glow of the Silver / Gold but is more even throughout the entire frequency band. At all times, it sounds effortless and natural. Strongly recommended !
Here they are installed in the Lite DAC60 (the large black cans -hard to miss!)
Because they are so large -they were close to the tubes which, of course, do put out heat (and these caps DO NOT LIKE HEAT!)
So I remounted them to the side and wired with Mundorf telfon coated solid silver wiring.
This will keep them far from the tubes and nice and cool.
When I had the Mundorf Supreme (regular - not Silver/Oil version) they were smaller and are not as sensitive to heat. They were fine I believe in the original position.
Here is the cost and size differences - the coupling caps require 2.7uF caps.
The Regular Mundorf Supremes - $46.60/pr from Sonic Craft DIY 30mmx56mm
Mundorf Silver/Oil - $165.30/pr 41mmx57mm
Now Vishay Roderstein Film bypass caps can be added to the regular Mundorfs - which I did and they did improve the sound. .01uF are only $1 each - so this is a very cheap addition to the regular Mundorfs. The Silver Oils are still much better - much more liquid with a fuller bodied tone.
The Vishay's are the little square gray box caps under the Supremes:
From the Humble Home made Hifi Cap review http://www.humblehomemadehifi.com/Cap.html :
Vishay MKP1837 / 0,01uF MKP 100VDC - 1% tolerance
Technical specifications: Metallised polypropylene, radial capacitor, designed for LC/RC filter circuits, coupling and de-coupling at high frequencies.
Sound: Many years ago I was tipped by Klaus Witte of Germany to try this capacitor as a small parallel cap for the Mundorf MCap Supreme. I tried them as a parallel cap for the tweeter series caps in my Progress speaker and I must say I was very impressed! To get straight to the point they don't change a Supreme into a Supreme Silver-Oil but they really do clear things up. I must admit I was sceptical at first as the value is only 10nF (0,01uF) - and the caps I was using at the time totalled to 12,6uF. The difference is most noticeable with classical music but also good quality recordings of jazz and fusion benefit: No change in sound stage width or depth but there is more concert-hall acoustics that let you get into the recording more. Not as liquid as a Mundorf Silver Oil but they did take away the slightly grainy edge from the Mundorf Supreme's. A noticable gain in clarity and transparency making instruments better separable from each other, the violins in an orchestra become a group of individual violins instead of one mass. Jazz drum brushes sound more like a brush than a "shush".
Humble Home Made Hifi review of the Mundorf Supreme's:
Sound: The MCap Supreme delivers an open and spatial sound with lots of depth. Good reproduction of the musical nuances with detail and depth from the high treble right down into the low mid-range without exaggerating things. Clear and transparent sounding cap with a good sound stage. They provide a good improvement in clarity, focus and dynamics compared to standard quality MKP's and sound "meatier" than the Mundorf MCap EVO Silver Gold Oil, more mature and a tad warmer sounding as well. The degree of improvement is comparable to upgrading to high-end cables and interconnects. I must say I was impressed when I first auditioned them several years ago and still like to use them. Where as cheaper capacitors get can lost when fed complex materal, the Mundorf MCap Supreme keeps the overview on things like a full scale orchestra. I also found that the Mundorf MCap Supreme mixes very nicely with Clarity Cap SA capacitors.
Verdict: 10
Review of the Mundorf Supreme Silver/Oil
Sound: The MCap Supreme Silver Oil is one of my favourite capacitors! I can only underline what Mundorf states: “…wonderfully spacious and detailed sound reproduction … full and smooth tonal richness and diversity. This capacitor's ability to bring out the finest nuances and the subtlest distinctions make the music sound more alive and “juicy”, …Wonderfully spacious music reproduction… ”. Music detail and depth throughout from top to bottom. Very smooth and liquid. To exaggerate things: it makes a standard Supreme Cap sound slightly rough!
Verdict: 11
Review of the Mundorf Supreme Silver/Gold
Sound: Nicely clear and transparent, rich textured treble, very spacious; front to back and left to right, very good separation of the individual instruments, deep black background, clean and dynamic, heaps of micro-detail information, the details get high-lighted a little but nothing to worry about. I know one could easily think that this capacitor must be good because everyone says so and it is very expensive but I have tried to keep my objective view and even so I am very impressed. Were I would describe the Silver/Oil as extremely neutral, I would describe the Silver/Gold as extremely natural if you know what I mean. Acoustic instruments like a viola da gamba sound really life-like. In comparison to the Duelund VSF-Cu copper-foil capacitor they can sound a little bright in the top-end, but this can be a plus point if you want to brighten up a dull sounding system or you just dig those so-called high-end recordings with bells, chimes and things. They are by no means harsh, just on the clear side of neutral sometimes.
Verdict: 11+
Review of the Mundorf Supreme Silver/Gold/Oil:
Sound: At this level we are talking about a really serious capacitor, so my findings are relative to other exotic types. They are richer and better layered than the Mundorf Silver Gold (without the oil) and they seem more open and more spatial. Compared to the Duelund VSF-Cu they are not as rich in harmonic overtones. The Duelund VSF-Cu creates smoother harmonics and a better midrange balance but the Mundorf Silver Gold Oil really excels in image depth - call it bowling alley depth! In direct comparison, the Duelund VSF-Cu sounds flatter (a bit more 2D) and a little rounded-off at the top. Like most Mundorf capacitors, the Silver Gold Oil has a slight hint of top-end emphasis, this probably contributes to the perceived spatiality and micro-detailing. But I am very happy to live with that, these capacitors are so quiet and really let you look very deep into the recording!
Verdict: 12+
I am considering trying the Mundorf Supreme Silver/Gold/Oil caps -they are approx the same size as the Silver/Oils but much more expensive! $240/pr!!! I really wonder if they would improve things to justify that much extra cost. The Silver Oils are already so good - how much better can this DAC sound!
Well the ratings (Humble Home Made ratings) of the different Coupling Caps - Stock Wima's -7, Mundorf Supremes 10, Mundorf Supreme Silver Oil 11, Mundorf Supreme Silver Gold Oil 12+
PS Last note - when ordering these caps ask for matching. It's only a small additional cost and they will pair the two caps (they are already with in 2% - but this will get them to within 1% tolerances).
