[Brand] Mundorf - Silver Oil (1uF/1200V) $38.20 (for 1uF) [Impressions LV] . [Rating] 4 [Impressions HV] 
I've been avoiding Mundorf caps for a while. They are the new kid on the block, and they seem to excel in goofy audiophile marketing (oil-impregnated Silver-metallized Polypropylene, special counter-inductance winding). But, even with that, they still seemed like metalized polyprop caps which, to my ear, aren't typically the endall of quality. If you look through this list, the best caps are the film and foil, and my favorites overall don't have any plastic in them. Further, the counter-inductance winding sounded like two caps in series, and really, if one cap is a bad thing, can two be anything but worse? Well, after a talk with Jeff at Sonic Craft, he convince me that these were the real deal and were worth a try. In fact, he said that other than the Sonicap Platinum, these were the best coupling cap he sells. So, I gave them a try and really all I can say is so should you. Like the Jupiters, these are into the class of caps where choosing one over another is simply preference. They are a step up in quality from any other plastic cap, or any other metalized cap, I have tried. They are crystal clear with a sweet midrange. Further, they don't seem to have the artificial paper in oil sparkle on top. Moreover, while maybe a tad warm, they really just let the sound of the circuit come through. With tubes that are raw sounding, the caps sounded raw and a little warm. With tubes that are bassey, the caps were bassey; with tubes that are sparkley, the caps were sparkley, and a little warm. In other words, (and unlike the Auricaps below which dominate a circuit) while they do have a character (all caps havea character), it is one that lets the character of the circuit through. These have now replaced some Auricaps on the output of my DAC
