I do not have direct experience with the Zephyr versus the Silver but do with the Onyx versus the Silver which is on the other end of the price point. The Silver was a great arm that I enjoyed for a while that was installed on a Origins Aurora table after purchasing it with the Onyx, the Onyx had a lot to be desired and almost kept me from going further up the Origin line, sold the Onyx and purchased the Silver, which I knew to be a good arm after having one on a Sota Cosmo III for a few years and loved it till I sold the table and arm. The Zephyr is in the next level up, the Premium level of arms, for Origin so I would bet it is better than the Silver by a good amount and that would be a no brainer. FWIW the Silver is one hell of an arm. Enjoy the music
