Yes, Jotun is on 24/7, balanced after market cable. Though I just realized something weird. Treble was getting tizzy/grating/harsh, more than usual. In fact, there would be times I could swear it sounded more relaxed and smooth, and others where it sounded grating/harsh, even with the same tracks. On a hunch, I turned off the dryer in our house what was drying clothes and the harshness immediately went away and it was smooth again. I generally don't mind bright amps/headphones, so Jotun/HD800 didn't bother me until specific times. I realized when the washer or dryer was running, or even if I had the lights on my room at night, the treble gremlins would come back. It's weird because I already have a power conditioner all my gear is plugged into (Belkin Pure AV), so maybe it sucks. I don't think getting a new amp is going to change the fact that the power in my house is fucking with these cans.
