RE: Problems with LM4562 Opamp in Tjoeb '99 cd-player

For power supply decoupling apps like this, nonlinear caps are OK and won't negatively affect the sound. This means cheapo ceramics are fine and no need to use audiophile quality caps here. In other words look for the relatively cheap ceramics instead of the high priced Black Gates or paper in oils. In fact there will be an advantage to using ceramics in this case due to the lower ESR typical in this material type capacitors.

X7R is a grade of dielectric used in ceramic caps. Not the most accurate mind you but again this app, power supply decoupling, does not require accuracy but lowest ESR per capacitance ratio.
