Soundsmith Zephyr MKIII vs the Othello

Hi everyone I am a newbie to the high end world of analog audio. Though I have been listening to records my whole life (born in 1964) I have never had a serious high end analog system so I am fairly new to all the brands and concepts. I recently put together a nice system consisting of a VPI Super Prime Scout, Threshold NS10 Preamp and a Parasound HCA 800II ampliifer. Speakers are refoamed vintage Snell J3’s. I bought the turn table with a Soundsmith Othello cartridge and I have to say the system sounds pretty darn awesome. I get the whole high end audio thing now and am running down the rabbit hole at top speed chasing the next upgrade towards honest realism. I was looking at upgrading my cart already from the Othello to the Zephyr Mk III. Can anyone tell me if the Zephyr would be a respectable upgrade from the Othello? Honestly the Othello sounds AMAZING and I can’t really see my system sounding that much better. Alas I am chomping at the bit to upgrade to that Zephyr. I have become a big fan of Soundsmith. They have definitely found a loyal customer in me. I was a big fan of Grado, but am now in love with Soundsmith and a fanboy of Peter Ledermann. Like Peter Snell and Nelson Pass, Peter Ledermann is an audio genius. In my humble opinion anyway.
