ZEN cartridge ?

All best Victor MC are direct coupled type: MC-1 and MC-L10 have almost identical plastic cartridge body to your ZENN, I’m curious why? 

MC-L1000 visually does not look like ZENN.

I own a Zenn mcz/2 and it is a wonderful cart.
I also own both Victor MC-1 and MC-5E.
it is quite remarkable how similar the ZENN and the MC-1 sound. Easily two of my favorite cartridges ever-so far...
unfortunately the MC-1 I acquired was NOS from the estate of Bill Johnson of Audio Research I just noticed the substrate the coil is printed on is delaminating.
it still sounds great but not for long.....

MC-L1000 visually does not look like ZENN.

in fact my clarification did not refer to aesthetics but to the principle of functioning of Zen not Zenn.  :)

 I just noticed the substrate the coil is printed on is delaminating.

when it deteriorates it will be the end, a lot is also due to the dust that settles in the space where the reels move.

Victor Direct Couple MC-1 cartride was introduced in 1977, then the MC-2E, MC-L10 (on my image) and finally MC-L1000 appeared on the market in Japan. The coil of the MC-1 is printed micro-coil made by IC lithography process, and sitting near the stylus! They are all quite nice sounding cartridges in my opinion. From my conversation with J.Carr (designer of Lyra carts) I’ve learned that while the MC-L1000 was certainly the most extreme of the range, that is not necessarily the same thing as musical enjoyment, many listeners would probably consider the MC-L10 to be better balanced, less merciless, and more musically enjoyable.
