^ ^ This.
OP, have you tried other solutions besides bringing the bars up/closer? Are you moving your hands around on the bars regularly? Are your elbows locked straight out in front of you while riding? What type of bar tape and gloves are you using (if any)? Are you doing any core strengthening work in addition to riding?
Before going through the expense of a new stem and/or adapter + bar combo, you might find that there are other solutions that will work for you to prevent hand numbness.
