My Mark Levinson 20.6 class A mono blocks pull 400 watts at idle and run 10x hotter than my Marantz 5 tube mono blocks. I would swear there is a fan in the amps blowing heat. I also noticed my electric bill goes up $100 a month to run the 20.6's. They are the best SS class A amps that I have ever heard.
How hot is hot when moving from class a/b to to a or tubes?
I am considering moving from a class a/b Luxman L509x to a class a or tube amp.
I have never owned a class a or tube amp, so have no experience of living with one. My kids are hopefully old enough and wise enough not to burn themselves, but I do live in an already warm house with bifold doors leading to a south facing garden. There is no escaping the sun, despite having uv treated glass.
My room is roughly 9 meters by 12 open planed living space. Equipment is, Luxman L-509x integrated, Zu union 6 supreme, 99db sensitivity (this is why I am considering a lower powered tube I can barely turn the Luxman up) music is played roughly 6 hours a day, more on weekends
who here has moved from class a/b and d to class a with or without tubes. What were the differences of things like:
warming up time
additional heat to the home
Running in summer time
additional cost to run
any considerations I should make before purchasing something. I will try in my home, but will need to free up funds
