Hi @Suedkiez
Not so silly question. 
Leaving device so it never goes to standby (auto standby = off)
- Pros - products with amplifiers built in are left on 24/7, Everything really is totally thermally stabilised, so best sound.
- Cons - Can’t easily shut up external inputs (digital, analogue). Product is lit up and screen is left on, until we auto switch if off after quite a few hours just as a precaution on the screens LED backlight. On very sensitive speakers, some hiss maybe heard.
Leaving device in server mode (server mode=on, auto standby = 20mins or similar)
- Pros - Product naturally goes to sleep when not in use, so lights etc. all go off.
- Cons - Amp is held in reset while in this state so there will be a warm up time for amp to get to peak performance (in my experience about 20mins max - different systems and user expectations will vary).
Personally I prefer server mode, but either are perfectly valid options.
Best wishes
