I have built the Pass Zen revisited amplifier as per instructions on the PassLabs website. The amp sounds great but I would like to increase both the sensitivity and the input impedance. Nelson Pass states that you can change R10 and R11 to set the gain but I am unsure as to what values I should use. Any help would be appreciated.
You can set the gain resistors at any value
you like, but as the impedance goes up, the
distortion of the amplifier increases at high
frequencies.
