OIMP capacitors are not to be confused with a typical "oil" capacitor. They have the speed, detail and articulation of a good poly film cap yet have the warmth and smoothness of an oil cap.
Being in the industry and the fact that I use both Dan's OIMP and Teflon capacitors in some of our products and/or modifications including being used exclusively throughout our EXtreme Acoustic Zen Adagio modification as well as being a ModWright dealer (no, we do not sell ModWright capacitors) I will not comment on their sonic character as it would only be viewed as bias.
