[QUOTE="Shonver, post: 566867, member: 34"] OK, so one audio instance... moving coil input. This is one I can accept as an undeniable noise case, due to the high gain involved. And, yes: I agree that using an appropriately low impedance design is the right approach here. Apart from this, though, I am keen to know if there have been cases where using special low noise resistors have made a significant difference. Personally, I only use metal film resistors for power amplifier and preamp stages. I have noticed, however, that noise levels can be fairly good (i.e, unnoticeable, unless you go looking for it) in circuits where no special care was taken and carbon film types were used. Thus my question. Note: I am here referring to subjective (aural) observation, not measurements, which I would not dispute. [/QUOTE]
