I built a 100Wpc dual-mono MOSFET power amp and wanted to switch it
from the pre-amp - at the time a Quad 33. I got a 30A solid state
relay, fitted it inside the amp, and switched it from the low voltage
supply from the pre-amp. Never had any thump or anything like.

The reason? Solid state relays only switch on at the zero crossing of
the mains, so there can never be any inrush current per se......

I sincerely hope the 'mains inrush current' doesn't get to the speakers on
any amp...
