Simulation isn't fast but if you let it complete and do an FFT on the last 30 seconds, it's 80dB down at all unwanted
harmonics.
There do however seem to be unwanted sidebands close in either side of 1KHz
Any suggestions for improvement?

Not that hard to make !

 These appear to be LTSpice, so why can't you use it to view my circuits?
 In any case if you can't simulate my circuits you won't be able to appreciate how brilliant a designer I am like Bill does.

The quantity of brilliance is only apparent when you can see the circuit diagram and work out what he is trying to do, which can take a while.
