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.

I'm not sure.  I believe NAD uses nCore, and in some cases hybrid NCore / Class H designs.  My personal experience is limited to IcePower.  I can't say it is a problem which extends any further.

Fair, Erik.  I nearly gave that amp away for a buyer friendly used price. I should've kept it and used it in a different system. It was a fine amp.  I just couldn't get it to sound right with my higher efficiency speakers.  Sounded great with the house brand PSB Imagine T2s.

I'm not strictly objective, but unless something passes a double blind test, it's simply opinion, which can be greatly influenced by cost and appearance.

I’ve always put mine in sleep mode, as for a reason to leave them on I have no idea.
