I would agree. As the sound of my system becomes clearer and cleaner I do tend to listen at louder levels than before. Really fine software whether vinyl or digital, also tends to lead to louder levels. One thing, my experience is that every indoor listening space has a maximum volume it will tolerate. If you get carried away with the volume, the sound becomes cacophonous. Ugh!
Volume Increase of decrease as system improves
Almost all of us have been on an upgrade journey with our systems. My question is as your system has gotten better has the volume at which you listen gone up or down. My personal experience is that it has gone up. I think because there is less distortion hence less fatigue at higher volumes.
