subsonic load question/supressor

I have a suppressor on a SCAR and PCC 9mm. Obviously still get the crack from normal supersonic ammo.

Looking at loading subsonic ammo. And bear with me here, as I am new to this part of the game, if I am shooting subsonic ammo, that negates the need for a suppressor, does it not?

I get shooting subsonic with a can will be incredibly quiet. But is there a middle ground to eliminate the supersonic crack while shooting suppressed, yet still retain some energy downrange? Is this asking for the best of both worlds a futile pipe dream?

I guess in other words, how far can I push a load, suppressed, before the supersonic crack appears?

Also, I understand the differences in powders and burn rates, but how does this translate to subsonic loads? What type of powder is optimum? I see Trailboss seems to be popular for .308?

I do not own a Chronograph. But I'm guessing it past time I pony up for one.

Thanks for entertaining me. I know there is a lt going on here.
