The MSR7 are not "thin" in the sound. They don't enhance one frequency over another. I do like a nice balance as well and I would hate if one area was lacking. I have some tracks I use to listen to the bass attack at the beginning of the song:Chris Rea - The road to hell part 2The Eagles - The Sad CafeAmos Lee - ListenThey all sound perfect with the MSR7. Ask if you can return them, but I'm sure you will love them!!
