I would say that SET oawners listen at levels they prefer just as owners of non SET amplifiers choose to do. I didn't listen at higher sound levels when I used Solid state or tube push pull, 75-85 db was simply loud enough for me in my home. We all have our individual level of comfort regardless of amplifier topology or power.Atamasphere if the SPL at shows Is indicative of your preferences (Atamasphereand Classic Audio speakers) that's louder than I'm comfortable listening to. But again no right or wrong at all just an example of how we prefer different sound volumes. What's ideal for one isn't suitable for another. I'll make the assumption that we as seasoned listeners know what we like.
