Hi,

I hope this post is welcome here (not about building/modding), but would appreciate your input. I have a new MC275 that I have been unable to stop listening to and am just smitten with. My original plan was it would be my 'special occasion' amp but it sounds so good I am not sure I want to go back to my SS source. Between working from home (for the foreseeable future) and night/weekend listening, I would have this on for 8-16 hours a day playing music, movies, and even YouTube videos (my 2-channel system is also my HT system).

I've read this amp is very 'kind' to tubes and seen people reporting amp tube life closing in on 10,000 hours. I am working under the assumption (for me) of ONE power cycle per day (on in morning, off at night), as it sounds like power cycles is the killer. Does this sound reasonable, or would you expect something less (or more)? I'm not scared to burn through tubes, but I've also read some great results upgrading the tubes (nothing crazy, new-production stuff) improves this amp further. I'm tempted to buy a full new set of tubes and just stash the 'McIntosh' branded ones that came with the amp (though the odds of me selling this are basically zero, unless I am dead or broke).

Thanks!
