That's interesting and I do know that even valve amps blew up ESL's on a regular basis. So this must have been Quad's reassuring answer to a farsighted concern.
The 2905's are supposed to shut down when they detect loud volumes but my amp has always shut down first. This time, an arc occurred for a different reason than loud volume but rather high gain between the amp and app transport. I couldn't hear a poor live Grateful Dead recording via Sirius XM and so I turned the amp up to 60 and the transport gain to 20 something and ouch!
