This is an older post. For me, the differences between F and FK series are very consistent.FK has a better texture (the richest), great definition/superior articulation and generates the blackest background. I can't imagine Havana without Black Gate FK! I have not felt the full effect of film capacitors (what is said about Rike S-Cap regarding the dynamics, texture and naturalness) until I installed these electrolytics.
