LONDON Decca, Tzar DST and similar cartridges

I auditioned the Tzar on a Reed 3p tonearm - can’t remember which armwand - and Reed turntable. The best cartridge I could ever listen to and hope one day to get. It benefits from a heavy mass arm as far as I understood.

Hey good morning.  I'm curious if any London Decca/Tzar owners have experience comparing their carts to the Soundsmith moving irons, and/or the SS strain gauge (i understand the SG system is not a MI cart)?  I'm interested in moving towards the MI carts for all the positive user experience shared on this thread and others.  I also like the idea of the strain gauge because in the words of Paul Cavalconte (NYC DJ), its perform's like a Decca that actually tracks.  I also like that its a system that removes the cost of a phono preamp, actually seems like a reasonable good deal.   I have not heard either in person (Other than on youtube clips and that Paul Cavalconte uses the strain gauge to rip vinyl for his radio show using the strain gauge).  Would love to read any users thoughts on comparisons.  Also, any London Decca, Soundsmith or Tzar owners in NE Ohio area that wants to spin some records, I'll bring the refreshments!  Thanks.

The LDR has a cantilever, it is just oriented in a different direction. The problem is that the groove must now lift the entire mass of the assembly and not just the effective mass. Thus, tracking and record wear suffer. There is a reason nobody else makes a cartridge like this. Only the British could come up with a design like this. The Tzar I have never seen of heard so no comment there.

Isamu-Ikeda made various cantileverless models in Japan, they are LOMC
