Dear @mglik : Good that you followed the rigth @tooblue advise.
Look, even with out the JC board the AI is better performer than the other one and you can know trhough its specs. The Zesto is really bad in the most important subject in any phono stage that's the RIAA weq. and its frequency deviation is over 0.5 db against lower than 0.2db in the AI and with the JC 0.1db. Other important characteristic is that the Zesto has very high output impedance that affects the high frequency where the AI has a lot lower output impedance.
Regards and enjoy the MUSIC NOT DISTORTIONS,
