Stereo100 not even close. Look at the chassis of each. The Stereo100 has several large capacitors for reserve power store. The amplifier excels at transparency and dynamics and sounds much more powerful than its 100 watt rating. In my system it has sounded more dynamic and powerful than two solid state amps, one rated at 200 WPC 8 ohms and the other 200 WPC 4 ohms.
Balanced inputs also make this one for the win.
The Carver is competitive to the Rogue Atlas Magnum, not the Stereo 100.
