Apart from the nasty schematic quality, I see this points:
- There are more poles (low-pass functions) in the circuit, e. g. 132 kHz (C4/R5) at U1.
- the OP output load is much to high. Fortunately, your are simulating only, otherwise you would most likely destroy the device or at least burn your fingers.
I suggest, that you start with a Linear application circuit, that can be expected to have meaningful dimensioning. Furthermore, a hand calculation of currents and power losses at some parts wouldn't be a bad idea, to my opinion, e. g. for the 2 x 15 ohm voltage dividers. Please consider also that high speed OPs are able to source high output currents and don't have a safe current limit like a LM741.
