probably not with the 200Vppss amp promoted earlier ( ;-p ) but I suppose there are KG amps out there with enough power to cause arcing eventually although I suppose the apparently larger DS gap used here may mitigate the issue a bit. Now, I wonder that most severely burnt diaphragms are the result of using transfomer boxes with high power amps rather than dedicated amps ?
ps: from wikipedia, 1500Vppss would suffice for a 0.5mm DS gap…

<<Partial discharge in air causes the "fresh air" smell of
ozone during thunderstorms or around high-voltage equipment. Although air is normally an excellent insulator, when stressed by a sufficiently high voltage (an
electric field of about 3 x 106
V/m or 3 kV/mm
[3]), air can begin to break down, becoming partially conductive. Across relatively small gaps, breakdown voltage in air is a function of gap length times pressure. If the voltage is sufficiently high, complete electrical breakdown of the air will culminate in an
electrical spark or an
electric arc that bridges the entire gap.>>
