What to watch for
The Lake processing inside is the system tuning. Swapping an amplifier without moving its Lake module configuration replaces the tuning as well as the amplifier.
Load verification will flag a driver fault before it is audible, which is only useful if someone is actually watching the monitoring during the show.
