I have an amplifier with a stepped attenuator. The gain of the amp is little too high and the comfortable listening level is between the 3rd and 4th detents. I don't want to change the amplifier gain and unfortunately I don't have the correct resistors on hand to make a proper voltage divider. The attenuator is 100k and the comfortable listening levels are mid-scale afterI inserted a 100k resistor in series with the input signal. I didn't hear any hum or other artifacts when I changed the input impedance to 200k.
Can anyone enlighten me on any problems of increasing the input impedance?
TIA
