Try to first increase both 3-4 times in value at the same time. While not gaining any voltage gain you will gain input impedance so if you lack in it when for whatever reason your input is low it will give you some extra edge. If it is some other effect then...
Also depending on the result increase the top one twice as much as you increaee the bottom one. This will add voltage gain on top the impedance gain. Do some experiments.
Oh. R704 might need to change proportional to the R703, the bottom one. It is the feedback, and if kept the same, the total gain will drop with R703 increase.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
