LONDON Decca, Tzar DST and similar cartridges

Yeah, it's just that tinny, microphonic Decca sound when the stylus hits the groove. If you are gentle, it can be minimized.

Hi @Bydlo glad you’re enjoying the LDR !
I’ve probably arrived late on this bit of this excellent thread, but just to let you know I’ve always had the sort of “squeak” you refer to- I think it’s normal and I recall reading a (gushing) Ken Kessler review of the LDR where he alluded to something of that nature too.
A couple of other points to throw into the mix : my LDR is mounted on an FR66 tonearm and I tried a few different headshells along the way. I’ve ended up with an Arche headshell , but the one that stood out for me with the LDR apart from this was the Yamamoto African ebony wood headshell which was really good with the LDR (in my system at least !).
This will sound OCD, but using titanium headshell screws in the Arche also made a material improvement, as did using good quality headshell wires (the aggolos silver ones being very good and flexible for ease of fitting).
Finally, I use Vertex AQ silver tonearm cable from the Brinkmann Balance into the Allnic H3000 phono stage set at 47k.I read the various stuff about changing that 47k impedance to a lower number ( I honestly can’t remember what but I’ll check and let you know ) and Vertex made me a bespoke cable that did that , and yes it again made a significant improvement (it was a while ago but I recall it pretty well got rid of any slight steeliness in certain high frequencies).
If you’re lucky enough to be able to change from 47k on your phono stage then it’s worth experimenting, although (and here I haven’t a clue what I’m talking about in actual physics) I’m told by Vertex that the true impedence is affected by the cable,  so it’s not just what the knob on the phone stage necessarily says. 
Best regards and enjoy the music !

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.
