Best Crossover Capacitors

i don''t do high end capacitors myself. no doubt they make a difference but i''ve used solen,audyn,jantzen,and dayton in my designs. my worn out ears can''t really tell a difference. i don''t go for bottom of the barrel but i don''t go nuts. inductors are expensive enough and there''s no getting around that cost so i will save what i can in caps.
