All,
Looking at the replacement of electrolytics in several second-hand amplifiers, I wonder whether surface-mount multilayer ceramic capacitors are a good replacement for a low-voltage tantalium where bias problems may occur (such as with C2 in a Quad 405).
The advantage is that they're small while large-capacity values are available.
Such capacitors are often used in digital (i.e., computing) circuits. From a noise and distortion perspective, are they OK for audio?
Thank you for your thoughts,
Jacques

Be aware that high-K dielectrics like Y5V and Z5U exhibit large changes of capacitance with changes of voltage and temperature.
I have a Mini-ITX based PC, which uses X5R dielectric capacitors as the output dc blocking caps on the built-in sound card. Distortion at high audio frequencies is low but the capacitors cause very considerable distortion on low-frequency signals.
