This would save including more opamps in the signal path. Any ideas or comments on this?
Given that you find the right circuit, it would be cheaper, better, simpler. Actually I cannot see any reason not to do it, if you are building the power amp anyway.

What exactly does your current PLLXO do, (asking is easier than getting my brain in gear to calculate frequencies)
I know that feeling well Al! I provides a bit of lift at the low end (60 Hz up) to counteract a slightly rising response) and a bit of lift at the top end.

BTW -what is PLLXO?

I hope you realise that there should be a resistor to gnd on the first opamp, and decoupling capacitors for the power etc. You probaly knew this, but just in case...
Yes thanks, I did but it never hurts to make sure.

Thanks again. It always helps to know what the the correct question should be in order to get the correct answer!

I don't know exactly how to do this but I think that I know a man who can
