According to the place of origin, it is divided into three categories: domestic, Japanese, and European and American. The price is basically domestic < Japanese < European and American. Because Japanese audio equipment products are relatively large and belong to the mid-to-high-end level, they basically use Japanese electrolytic capacitors (which have technical advantages and have the advantage of not being transferred to outsiders).

Brands: Japanese Nippon Chemi-con, Nichicon, Rubycon, Matsushita, Hitachi, ELNA Erna/Yina), Hong Kong and Taiwan series LELON, SUSCON, TEAPO, CAPXON, SAMXON, domestically produced TH, Beryl Emerald), Acon (Zhongyuan), Chang (Warwick), Xunda (Xunda), etc., European and American ELEBASIC, ITEDCON, KENDEIL, CDE, BHC, EVERALPHA.

For electrolytic capacitors for audio products, it is recommended to use domestically produced electrolytic capacitors for mid- to low-end brands. For high-end products, it is recommended to find Japanese designated agents. European and American brand capacitors are not cost-effective due to small market demand.
