I typically listen at the 65 to 75 db area. But I occasionally crank it into the 80db area, it sounds great.
If you are listening at an average spl of 85 that is very loud. If you are talking about occasionally peaks touching 85… that is just loud.
I had some kids come over and crank it to…. Loud… I didn’t want to go in to measure the spl, it was too loud. No evidence of running out of power.
I found when I switched over to the ARC amp from a Pass 350 (Wpc). I actually listened at lower volumes because the music was more satisfying at lower volumes.
