Question about Primare A10

Might as well ask while I'm at it... [will also post to uk.rec.audio]

I heard a slight pop in my JMlab 905s yesterday followed by a loss of
audio to both channels. The amp was idling at low volume with a source
connected. It is cold here -18C outside, 11C indoors, and the A10 is
situated near an air vent (and was cold to the touch). The display
illuminates but on power up I no longer hear the relay switch click.

Does this suggest any obvious fault??
