Just some observations as a 20 year plus carpenter.
At first glace for a sound controlled room, those gaps would cause me concern.
There is no reason you can not stuff some fiberglass insulation in there, I am sure his concern is over stuffing and bowing out the jamb.
The insulation will do a little to help, but not a lot.
That gap looks pretty big and has a good to and from from top to bottom, indicating something is out of level...fairly common situation.
While it is fine as is, it looks like that gap is large enough to put some full length wood in there to fill in.
That gap looks like it is pushing max size before full size/length wood is called for, rather than a stack of shims.
How much any of this will effect soundproofing, I do not know..........but it is common to see this on some doors and it definatly pushing max gap you would use shims in.
Perhaps lightly pack some fiberglass in there under installer supervision or have him do it and then apply some acoustical sealant. If you go against his suggestion it is possible he will in the future blame any problems with that door on you. He might not, but it would be best to get him to do it if possible.
At the end of the day, will it even matter in sound levels outside the room.......but the possibility it could would cause me to take action.
