Used TechDAS Air Force III vs New Feickert Firebird with Kuzma Safir 9 vs SME 20 MK 2

@rauliruegas

Also what unit is cu? I feel bad even asking but it’s been a while since my electrical engineering classes!

@chauncey have you made a decision on which table? White Stabi R?

Dear @chauncey : Yes, your SME tonearm will be a good " husband " for that lady. That tonearm is an excellent design for almost any cartridge, I the V and listened that one in the TechDas TT.

In the other side, cu means compliance units.

Btw, this is what the designer of the Safir posted in his site:

" All four points of the bearing have minimal friction and zero-play in all planes of movement, thus ensuring that the cartridge platform and the cartridge itself follow the grooves of an LP with extremely low friction and minimal vibrations. "

The tonearm is a 4 point unipivot design and even with out any measure where the designer could confirms that zero-play/low friction we know that unipivots normally has low baring friction but unipivots always has a " chatter "/rattle self movement due to the enormous/tremendous forces developed bay the cartridge stylus during play trying to folows those "Himalaya mountain chain " that are the LP groove modulations. There is no true/measured evidence at microscopic scenario where we can find out that the 4point tonearm has not that chatering under playing condition and through high velocity LP recorded grooves.

I know that almost all 4point tonearm designs owners and reviewers " like " what they heard but it’s not enough for me that " like ". Well this is me and others differs from me and it’s ok.
