Quick resistor question...

The opposite is true. MF resistors have far better tempco's than
carbon types.
But if You are asking about "always", then there are exceptions.
Many years ago there were MF resistors from a large German
shop that were more noisy than carbon types. But this should
be the exception.
BTW, most people underestimate the effect of resistor
*value* on noise. Building filters for my vocoder with 470k
resistors, the resistors produce more noise than a 741 opamp.
(I used TL074, for other reasons, however).
