VAS (Steven Leung) cartridge repair/retipping service?

Any experience with or opinions about VAS/Steven Leung repair/retipping service?  Not for VAS cartridge.

Well, based on the very positive comments here, I sent my ZYX Airy 3 out to VAS today for an inspection and possible boron cantilever/microridge stylus combo.

please let us know how that works out for you.
I have nothing but high praise so far.
I have been sending my Koetsus to Van den Hul for decades.

I lived in NYC for 45 years, and have been living in the Hudson Valley for 3, and though I am now minutes from Soundsmith, he is not cheap, in fact he is far more expensive than sending it overseas including shipping. And I find him difficult to work with.

Is anybody in a position to compare the quality of Steve's work to Van den Hul's?

Has anybody sent a Koetsu to Steve, and is able to describe the change in the sound characteristics, if any, before and after repair?

Thank you all in advance.
this thread has been very helpful. how close to "new" or "original" can a rebuild get? have some of you found your carts to sound better than original versions? thank you.
