Solid state, leave on 24/7. Tubes, turn on to warm up 5-20 minutes, turn off when done. Hybrid (DACs that think a tube will make digital listenable) no tube on Earth can do that but hopefully the tubes are cheap because being digital absolutely must be left on.
This is both for sound quality AND longevity. The greatest wear factor with SS is thermal, which is reduced by leaving on. The greatest wear factor with tubes is being on, which is reduced by turning off.
So the moral of the story: buy tubes, buy analog, turn off when done.
