Thank you.Hope they last well.
You will find they are very transparent to recordings. They show through concert hall ambience better. The only thing is with your preference for amplified music and because you like it more in room in front iirc, as compared to mid hall or back of the hall, Tak do that with a beefing of the midrange
I'm finding that the Elrogs make images more palpable and holographic and pull them out into the room a little more. There is much better layering of depth in the soundstage and, you say, I am hearing lots of small and ambient details from the back of the stage that I never knew were there.
