I would like to reduce the gain of the Nbip300 power amplifier. Would I be right in thinking that reducing the value of R19 ( 27K ) is the way to go ?
Well yes as its a reduction in gain and the feedback will be increased this will increase the fidelity , keep in mind though you might need to change the value of the compensation capacitor -C9 ( VERY slightly ) in case of insipid instability .
JLH actually used this feature in one of his mosfet designs as a balance control .
