Yes, generally pro amps will have more current capability than any consumer amplifier. These amps must deal with difficult and heavy loads for prolonged periods without failing. This means they need lots of output devices, lots of heatsinking (and / or fan cooling) and a stiff power supply.

One potential downside of some pro amplifiers is their noise level (electronic and because of the fan), and that they are not necessairly designed to sound the best - their focus is more on reliability. There are good sounding pro amps out there, but I can't name them off the top of my head.
