KISEKI PURPLE NS your reviews....

I honestly do not know what he did exactly to repair, all I know is it worked and it plays perfectly.

Now a friend has just acquired a Kiseki Purpleheart as an ex demo with 100 hours on it so hopefully will get to hear it very soon.

Well one can attribute all kinds of characters to the persons involved
or to the parts of the the cartridge involved. Regarding the last
mentioned kinds one need to realize that cantilevers/styli combos
are made by supplier to both; the cart producers as well repair
services. They all need to glue this part in the (aluminum) joint 
pipe on which also the coils are fastened. So if there are differences
in the ''art'' of the gluing the cantilevers in the joint pipe then one
should explain the '' árt differences'' and not declare other members
for stupid. This is to easy way out. 

Touché. I don't see why an experienced retipper, having access to the same parts supplied by the same jewellery companies, couldn't perform the job in the same way as the person or company who designed and built it.

One of the reason @edgewear is that some important parts produced 30 years ago are not the same (or don't even exists today). And since you're not a re-tipper yourself you never know. I never owned Kiseki, so i can't comment on this particular brand. But retipped cartridges are often on ebay almost unused as the OP pointed before while the originals are not always there. And don't forget about some exclusively made parts for big cartridge manufacturers. 

Re-tipping cartridges discussions...how does that address andychris’s question about those who have actually had a KPH NS? Just sayin!
