Assuming this is just an audio coupling cap then no, "a really good cap" makes no difference. At least, no improvement. "A really good cap" may sometimes be too large (and so introduce too much stray capacitance) or too unreliable (such as almost anything with a paper dielectric).djn said:In this particular application does a really good cap make a difference or is a run of the mill cap work?
I don't know if that question was intended for me, but if it was I don't recommend brands because I don't attach importance to brands. A brand is merely a name on the outside, and nowadays it tells you almost nothing about what matters on the inside. A century ago brands mattered, because Blogg's widgets were made in Blogg's factory by Blogg's workers so when you saw a widget labelled 'Blogg' you knew it was either genuine or fake.djn said:What brand to you recommend D?
