Hi, all!
Is there a difference between the feedback in this amplifier made with resistors: [(200k/10k) +1, and [(20k/1k) +1], if there is in what? thank you |

higher value resistors have more noise. and the lower input "gain" resistor will also reduce phase distortion caused by input capacitance.
I dont know if it would be enough make any audible difference though, i never tried different values than the recommended ones. |
