I've only heard the original Zesto. It's noisy. Bass is not that great. It's ugly and the build quality is poor for a $4300 device. The Allnic is tiny, uses the same step up transformers as their much higher end phono stages, quality materials throughout, 4 MC settings compared to 2 with the Zesto. The Allnic is more lively and fun to listen to, the bass is incredibly good.
