I wouldn't say I misuse my equipment but at times it would probably qualify as underused. Particularly in the warmer months when I spend more time outdoors. I am constantly tweaking things though. I adjust the sub from time to time and if the speakers get moved I have to go through the whole process of placement again. Turntable settings or tube changes happen less but they do need adjustments at times. It's all part of the process and something I enjoy so no sweat.
I can confirm that my system/systems are about to get a workout tonight!
Happy New Year!
