I've got a question about the different power source of the voyager. Does using different source affect how it sounds?
 
Im not sure if it is me hearing things or not, but somehow when I use it outside with my ER4P/S, especially the S, I find that it gives me more fatigue on both flat and contour than when compared to plugging it into the power source. I've used my ER4P for years and recently get an impedence adaptor, turning it into the S version. Im loving both P and S, but somehow it felt more "smooth" listening to it off the power source.
 
Does it really sound different or it it just my mind playing tricks on me?

I preferred the sound using the 9 volt battery. Is your amp fully burnt-in?

Nope, Im hearing it normally portably by day and plugging it into the power source and run pink/white noise while Im asleep. And of course giving it ample rest time (If it ever needs any, IDK) when I am not travelling in the day.
