Its all relative. For sure SS Class A runs hotter than A/B. Digital amps run cooler. Tube amps run usually hotter than all three, except perhaps for ghdprentice, but, for example I run a 40wt tube amp 10 to 12 hours a day. Puts out a bit of heat but really doesn't warm my house much as far as I can tell, nor does my A/C bill run high. The up side is in the winter I keep my house at 68 degrees and if my hands get chilly I just walk over and put them on the transformers, not the tubes!). My expense is I go thru a quad of tubes every year and that can be a bit pricy, but it was worse when I ran a big tubed amp and it was two quads. The enjoyment I get from music greatly exceeds the small additional costs involved in running the equipment.
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
