Silica Gel between the panes worked well.
Beware that the standard HVAC specs assume a leaky room and not an oven which is what a studio really amounts to. You need to move a LOT more air. The best way is with a relatively high speed fan combined with a muffler system. Slow "acoustical spec" fans generate LF noise you can't do anything about.

The HVAC system seems to be well-designed. The fan is definitely high-speed, as I can observe it really cranking when I'm in the basement. I can't really hear it at all in the live room. I do hear it a little bit in the control room but, for me at least, it's not a problem.

Third time was the charm. Guy showed, totally professional. In the glass business for forty years and has even done several corporate studios, as well as quiet glass installs in corporate environments. He mentioned a type of glass with a thick plastic laminate that is being used in sound mitigation. So now I am waiting on a cost estimate.

You still want two different thickness panes.

Yes 2 different thickness laminated panels with pvb or similar interlayer.
Then the same again in the other wall leaf with acoustic foam lining the internal jambs of each leaf.
It's bass frequency that are the hardest to stop.
