Yes - Steeper power output (speed times torque) is determined by the power supply voltage and the motors inductance. The motors output power is proportional to the power supply voltage divided by the square root of the motor inductance. Higher voltage will give you higher speed. Doubling the voltage will double the torque at any given speed and roughly give you twice the usable speed range. I routinely run steppers at 70V or more. I don't use Gecko drives the - their upper voltage limit is on the low side for some applications.
