After reading reviews of the two cartridges, I believe they confirmed my opinion. The Delos reviewer's spoke glowingly about the specs, detail and everything that makes a cartridge special, but they never mentioned what kind of music they were using to review the cartridge, while the Grado reviewer mentioned a jazz vocalist.
The Grado reviewer stated that the best moving coils still have more apparent "life" and dynamic energy than the Grado, but this sound is colored and exotic.
That's the difference between not only the cartridges, but aspects of music the listeners find most appealing. "Way out" music would be more exciting with a Lyra than a Grado, but when it comes to the soul of a jazz vocalist like Carmen McRae, nothing can beat a Grado. The difference between which cartridge enhances the music you listen to the most is the factor that should be the most important.
