I had to hear it. So I built it in on a spare headshell. On my cheapest arm. I had to take the picture upside down from the other side. Third arm ...
I picked a classical album from a Readers Digest boxset of romantic music 'Sheherazade'. These are really cheap but amazing RCA recordings. De Falla - Three cornered hat (Sombrero de très Picos) and El amor Bruno (the enchanted love).
First second I started playing it already sounded astonishingly good. Straight into the MC input on 47 Ohm. My least favorite option but the most versatile input for switching headshells. I'm now playing via my silver x-former. I don't know what they used for the damper, it looks like transparent silicon, but it sounds good from the start. The ceramic cantilever certainly is very stiff. The nude diamond is glued to the top with a blob of metallic looking glue. I checked the profile with a microscope and it looks pretty sharp. Not a simple elliptical. So the whole thing might not be super light but it certainly is stiff.
The sounds is very open and has a great sense of space and dimension. The sound is very even, balanced and natural. Good microdynamics. The soprano went well with just a hint of stress (I only did sideforce on the fly with thread and weight). Highs are wonderfully smooth and I'm amazed at how quiet the record sounds.
This was a blind buy. After the first model that I knew nothing about. I can buy another one of these for the same money as getting my broken Koetsu retipped. Yet this one is on the same level. Only it's a little less pretty than the Urushi. But the sound is better. (hard to compare from memory but I do not feel I'm missing anything).
