what brand ?
they are more expensive and less transconductance than 150N from infineon
but they are usable but in simulation they were less efficient

given the price it would be necessary that it is sorted of origin, impossible to order 50

I did not try to remove the 100.0 uF capacitor. I want to put 2 uF of Wima instead.
Very interesting result, thanks for sharing. This is just the kind of detail you can only sort out by building and listening, I think.
In theory, the cap is there to keep common mode supply noise out of the front end. However, I've seen in simulations that removing the cap actually reduces even-order harmonic distortion. That could be what you're hearing, or it could be that removing the cap cleaned up the sound by removing supply noise that the cap was coupling into signal ground.
Either way, I'm OK with removing the cap if it improves the sound, as long as it doesn't result in common mode oscillation. You can check for that by watching either output terminal to ground. If you see oscillation, you could try jpatay's suggestion of using a smaller cap value in place of the 100 uF.
