The compactly built Mundorf MCap EVO Oil is a big step up from the basic MCap EVO Aluminium and actually it is my personal favourite of the three EVO type's although it's more expensive brother, the EVO Silver Gold Oil, does still excel in fine, airy top-end detail. I found the MCap Evo Oil to do especially well on vocals, male and female voices come out well rendered and relatively natural sounding with a certain richness. Wind instruments (brass or wood) also sound convincing with the EVO Oil, they seem to have a natural edge to them. Image depth is another strong feature of the EVO Oil although not up to the high level of Mundorf's Supreme range. All in all the MCap EVO Oil seems to be the best overall performer of the EVO range unless you are into piano music - then the MCap EVO Silver Gold Oil scores lots of points for top-register clarity. Brighter than an Intertechnik Audyn Cap Plus that costs roughly the same but at the same time not as full sounding. I found that the EVO Oil likes to be mixed with Jantzen Audio Superior Z-Caps, the slightly bright nature of the EVO Oil blends well with the "boringly" neutral but spatious sounding Superior Z-Cap. For example when used for a large value midrange series capacitor: mixed at about one third Jantzen Audio Superior Z-Cap and two thirds Mundorf MCap EVO Oil, together they form a well-balanced rich and spatious combo at a reasonable price.
