Esco cantilever/stylus mods for Zu Denon 103R

Downunder, I really admired the Orpheus in it's day, but was fully aware of it's overly neutral nature. Personally I always preferred the Lyra Parnassus, loving it's liquid tonality and lithe bass, but couldn't get on with the Lyra Skala or Helikon which I both felt were a little too ascerbic esp. at the top end.
When I heard the Zu 103 three years ago, I really felt I was getting a lot of what made the Parnassus special, in a really user friendly package (dead easy to set up, sounds great out of the box). And the move to ESCCo modding has really smoothed out any rough edges the stock Zu 103 demonstrated in the treble.
Now I'm getting a sound that leaves me wanting for nothing else.

Yesterday, I sent my Zu 103R (lvl 2) to Soundsmith for their top cantilever and diamond. I am thinking that this is the equivalent of the ESCCo mods discussed here. This cart had been out of service for about a year because of a sweater-sleeve circumcision of the original cantilever. Now I can't wait to get it back to hear the results.

ESCCo are in the UK, Soundsmith the USA. This consideration as much as anything will swing most people's choice.
Where ESCCo may score over Soundsmith is the fact they provide diamond tips from scratch ie a more bespoke service, whereas Soundsmith provide from stock.
My ESCCo Zu 103 is still playing the role of giant killer, blowing my Orpheus out of the water.
BUT, I am a BIG fan of Peter Lederman at Soundsmith, and am actively considering his Straingauge to go up against the Zu 103. We shall see (hear).

I'm very curious about Soundsmith vs. Expert for the mod. I'm heard a lot about Expert from Lencoheaven, but mostly from European users. So is it any better than Soundsmith? IMO Soundsmith does great work. Could Expert be any better?

Suspect it's all in the same ball park. Soundsmith and ESCCo both have long and distinguished histories. They both have great feedback. I get the impression the actual diamond tips are more bespoke with ESCCo, but beyond this I can't help.
All I can say is, that for the price, the end result is fantastic, and the quality of work/customer service exemplary. Let's hear from some happy Soundsmith retipped customers.
Can't wait to compare to the Straingauge.
