I had a pair of Monarchy Audio se-100 Delux class A mono block amps. They powered a pair of Usher floor standers. Even at moderate volume the amps barely got warm. Amazing amps for $900 I bought as factory refurbs/upgraded. I once brought amps to my friends home to power a pair of Maggie’s. The amps definitely ran hotter to the touch but not extremely hot. So in my situation guess it depended on the speaker load
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
