Esco cantilever/stylus mods for Zu Denon 103R


I've just learned of this mod a few minutes ago, but I haven't been able to turn up any info as to where and how to acquire this service.

Appreciate the help, thanks, regards,

Just a little update. The basic Zu 103 in my opinion is a bit of a giant killer, with tone and dynamics right up there with the best MCs, just lacking in a little detail retrieval and soundstaging.
The ESCCo mods have taken all what's best, tamed the stridency apparent in the top end with a fair number of discs, and replaced it with a lush sweetness that really complements the unbeatable tonality already present. However the first few days' listening revealed a little undue softness or lack of urgency in the sound.
Now, a few days burning in has resulted in an elimination of this softness and I'm getting a much needed dose of incision.
So I'm now getting a cart with real involvment, tone, excellent but not spotlit detail retrieval, and a perfect balance of sharpness and warmth.
In direct comparison with my 4x pricier previous fave, the Transfiguration Orpheus, there's just no contest - in no area now does the ESCCo Zu 103 fall behind. In fact it trumps it pretty comprehensively.
Hi Spirit. Great to hear you enjoying the cart.

A friend of mine also had a Transfiguration Orpheus. He has a Monaco table with Triplaner.

He bought a Clearaudio Maestro which is around 1k - he too has similar thoughts on the superiority of the Maestro over the Orpheus. He sold his Orpheus.

I am not sure if this says something about the overachieving cheaper cartridges, or the Orpheus being a underachiever. Probably a bit of both.

I am going to have to put the esc'd 103r onto one of my tables again.

Cheers
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).
