I generally leave mine on throughout the day, and only turn it off overnight. I can’t tell much difference between morning and night (when it’s been on for 12+ hours), but I definitely enjoy my evening listening more than morning. Could be a subtle difference that only registers subconsciously.I probably mentioned this previously but i do think the SA1 sounds tighter with a bit more focus and detail when left on.
Even a few hours after being initially turned on it is still not at its best. Of course its a subtle change but noticeable especially on a more relaxed sounding headphone such as the ndh30.
Have done this many times with the same observations.
