Just replaced the electrolytic Bennic caps in pair of Spica TC-60 crossovers with Audio Grade Polypropylene. Did it after reading that Spica designer, John Bau, approved of that upgrade. As an Engineer, long time music lover and amateur audiophile always held a healthy skepticism toward "golden" eared experts that claim to be able to hear the airiness of a gnats wing flapping. Although, do understand that good design and proper component selection makes a difference. Well, my subjective ear test after the crossover mod was quite surprising. Chose the following as the first test due to listening to both shortly before the crossover mod. First, Dire Straits "on every street". First noticed that the right speaker seemed louder. After a couple tracks realized the right speaker just sounded better, "cleaner" for lack of a better word. By the end of the last track had to conclude everything sounded cleaner. Individual note beginning and end were clear, where previously a stream of tonal change. Next listened to Pink Floyd "Dark Side of the Moon" vinyl master recording. Simply a new experience. The Sax on "Money" clear and clean. All tracks revealed something new. I am in no way a "golden" ear, but there were real differences. Replacing electrolytic capacitors in a speaker crossover can yield positive results.
