Bigger image, more open sounding, especially in the upper mid and top. 7520 is a more compact sound.
The midrange is the Shure's real strong suit. I have never heard vocals sound more lifelike than what the 1540 portrays. And since vocals are a midrange item, and most music resides in the midrange, you can imagine why I keep listening!
Thanks. How would you say they compare in terms of detail retrieval. And how do the highs of the 1540 compare to the 7520? When listening to the 7520, they sound extremely detailed to me, every little nuance can be heard (even at low volume). Am curious how the 1540 performs in this area.
And how does the bass compare between these two?
