Hi, guys and - if any - gals ! Long see no time - or something in that sense.
I took a "virtual tour" of the recent Munich High End - via videos on analog posted by MF on YT Tracking Angle channel. About 6 hours total... ; but it was worth it.
After having to "endure" the generally astronomiically ( high 5, not that high six figure in price tag .... ) priced but nevertheles "interesting" gear in the first three parts, there was a revelation in Part Four :
Below I include all I could find on this spectacularly ingenious tonearm, the SUPATRACK Blackbird :

In case you don't "get it" from the above ( WELL worth the time for reading/watching ), here a nice explanation of the Kuzma 4Point bearing principle - as a teaser for the upcoming review in The Absolute Sound of the Kuzma Safir 9 tonearm:
The SUPATRACK Blackbird achieves - as one of the very few arms ever made available - totally stable pivot with negligible friction - something no ball, air, knife edge, unipivot, gimbal, ( any conventional bearing one might think of ) bearing system can claim, let alone achieve.. This or thereabouts performance level has been hitherto reserved for the select few ( Kuzma, Schroeder, apologize for any I have left out that do have bearing system preventing any free play, no matter how microscopic ) arms priced several times the price of the Blackbird.
When it comes to the effecive mass of only around 10 grams, it stands alone. This allows for the use of high(er) compliance cartridges - and in case you need a heavy tonearm, it is possible to add mass almost ad libitum. So, very versatile design.
It is a breaktrough like we have not witnessed in a long, long time.
One might balk on the non-existence of a VTA on the fly and/or micrometer for the same purpose - but, at the price, one should be reasonable.
