Sierra-1Nrt


Hi,
I'm new to the world of good music, so I have more questions than
answers. I want to replace the Sierra 1NRt one of these speakers: Carbon 7SE and Merlins TSM MMI, will be any improvement?
I want to hear a good solid middle and a 3D scene.
My system, power source Sphinx and Naim CD5XS
