Its true that some tube devices have rep for running tubes harder than others and individual tube life varies so it will vary but still worth noting.
I’m on third set of tubes in ARC pre-amp that I’ve had for four or 5 years now. It has 3 tubes in main pre-amp section and 3 in phono. The tube in first slot in phono section is the one that matters for phono noise levels I have found and needs replacing most often. I elect to not leave the ARC on when not needed to preserve tube life in taht I do not find warmup to be a significant thing for me. You would think most tubes have a long life and would not be impacted by an extra hundred hours or so but I’m sure it varies.
Bel canto amps (Class D not tube) stay on most of teh time unless away for extended periods. Same with BC c5i Class D integrated I have. Bel Canto actually recommends this I believe.
The devil is always in the details and usually varies case by case.
