Mine volume has gone way down. I used too have a system that had to be turned up to bring out the smallest detail. Now my background (noise floor) is completely silent and I can hear more detail than ever at low volumes. I'm thankful this is the direction it went.
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.
