I have a Carver 5X100w amplifier hooked to my Rotel Surround pre-amplifier. I turn on and off the Rotel - it does that with the TV remote, but the carver stays on all the time. Every once in a while I'll turn it off, but for the most part it's always on. This thing is over 30 years old and quiet as a mouse. That is my surround system, not what I listen to music on. My stereo is all tube except the streamer and the Schiit Loki Max - which I never turn off.
