What Would Be the Reasoning Behind Leaving Class D Amps On?

I think my Marantz Ruby integrated sounds better if it is just permanently left on.  I'm a bit of a tubehead, but I've had 2 other Class D amps and I recall them sounding better left on. 

I've seen a handful of manufacturers that even recommend their Class D amps be left on--e.g. PS Audio, etc. 

In addition to the potential improvement in sound quality, I suppose keeping caps and things on might be easier on them too.

Do you agree?  Do you know why this may be true or at least the theory behind it?  

Thank you in advance!  I'm super curious about this stuff.

It's quite simple. Class D amps when on, they're just standing by and using little to no power and could stay on and on and on endlessly

it’s been said multiple times on the forums that it’s best to leave solid state / class d amps on all the time as it sounds better.   turn off / unplug solid state equipment if going out of town or bad weather is coming.

tube equipment gets turned off when not being used.

So yes, and I've researched the threads. But I haven't heard the basis for why Class D might sound better.  I get little to no heat, they aren't tubes, etc.  

What's the science behind why they sound better.  Just curious.
