SRPP using beefy depletion mode IXTH16N10D2 mosfet instead of LU1014D

I will take one last stab at trying to use the IXYS16N10D2 depletion mode mosfets as a drop-in for the LU1014D devices which were originally provisioned in this SRPP based design. I started to sim with them and find that they are working in simulation but with high THD. My objective is try to re-use the PCB enough for testing them revise them if I ever get it working better to produce 10-20w into 8 ohm with lower THD.

Any design advice, encouragements and suggestions are welcome!
