Hi good folks! I have the Drop THX AAA 789 amp and I have two sets of headphones. A 35 Ω and a 23 Ω that I keep plugged in at all times both in the SE ports. I haven't noticed any volume change when I take one out while listening to the other one. Can the amp effectively drive both at the same time efficiently even when having different impedance? Could there be any issues on the long term if I do this or should I use just one at a time. I've noticed that the amp gets slightly warm. My use case is I work from home and I use one for music and the other one for meetings. Any potential issues driving 2 different impedance headphones from the SE outputs from the Drop 789 at the same time?
