Most other amps cannot deliver the voltage on the load that SD amps can do... These are voltages where you can still see an SPL gain, despite clipping: SD12kD = 200Vrms, SD16kD 210Vrms on the load. (depending on the impedance, of course).

i think it's more of a sd/alpine issue. most other amps don't have that problem.
