Not true, all SS gear needs to be on a minimum 24 hours, preferably in stand by mode. Tube guys will swear by that too. Why do you think most hi end gear has a power switch, then goes into standby?
Disconnect or power off the circuit breaker
Have you noticed that when you" disconnect" or "power off" the circuit breaker of your audio stereo system (for about 2 hours) , the sound is better after restore or reconnect electricity power ? Looks like it makes a kind of reset . Do you experiment such effects. Do you have any explanations ?
