tone arm bearings

I played this album a few times on my system before adding the Zephyr MK III ES. I found it far superior to the CDs I'd listened to, with excellent tone on Miles' trumpet and a deep and wide soundstage. But when I listened to it the first time with the Zephyr MK III ES, it was another level of cool. Right off the bat, the surface noise was down, significantly. Secondly, the soundstage was deeper and wider than I have ever heard on my system before. James Cobb's snare had more snap and his high hat took on more air. Song after song, I was completely engaged in the music.
