Changing approach operating tube based system in current telecommuting environment

Im seeking advice answering a question on whether to adjust my Audio system operations approach during the current work from home environment i find myself in for an unknown period of time. Im one of the very lucky people who has been able to relocate his office job and work from home. I know many who cant do this and find themselves out of work, so i don't take my situation for granted. I’ve moved my company office computers and telecon equipment to the “man cave” located upstairs in my home where i can work while playing music on my mid-fi music system. Here, i mostly stream Tidal smooth instrumental jazz from a Lumin D2 feeding a Primaluna Dialogue HP integrated amplifier to Goldenear speakers. Prior to working from home, i would come home from the office turn on this system, enjoy an hour or two listening to music, then turn everything off at the end of the day. Now, in the course of a 10 hour work day, i turn the system on in the morning, play backgound music, mute during multiple telecons ranging from 30 minute to 2+ hours, then turn it off at the end of the work day. So, here’s my question, sound quality aside, what is better for my systems longevity; should i turn the system (really boils down to the tube amp) off for the times i’m on telecons turning it back on afterwards, or should i just continue leaving it on the whole time as i have been and only muting or pausing the music during these telecons?

Thank you in advance for your advice.
