Yes a for a day an a half.
after I turned it on for about 2 hours, then I started to play before playing music.
Pathos Heritage
I just got my Pathos Heritage for my home in the USA, but I am experiencing something I have never seen before; when I first plugged it in with the volume at half it sounded pretty low, kind of scary low for a 80Wpc amp running Avantgrade Duo Mezzo XD speakers or Tannoy Kensington.
After running it for about 100hrs the loudness dramatically increased.
I have owned and own quite a few amplifiers and never seen something like this before.
‘this is REW’s measurements at the first few hours
and here after about a hundred

I hear you, I am more interested in understanding what electrically could have happened that the amp almost double SPL gain. I can't think of an electrical reason.... I understand that sound will open up and get a given signature with time but gain? It has never happened to me and I have and had own quite a few amps. |
@ghasley Those 2 readings I posted are for the exact same volume setting just at about 100 hours of run time, that is what I am curious. If it was at different volume then it would not be a problem. I am not too worried, more curious than anything else, because none of the amps I ever had, doubled the SPL at the same volume setting after just a few hours of running. |
