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

Sorry I haven't spent a lot of time investigating cartridges yet.  What is a high compliance cartridge vs low compliance?  

What I would like to use since I already own it!  Is a Mutech Hayabusa MC Cartridge.  Thoughts?

Dear @chauncey  : The cartridge compliance along the cartridge weigth numbers makes " differences " with the tonearm you will " marry " it.

High compliance cartridges normally ( everything the same. ) are has better cartridge tracking abilities that means can pick-up " more " music information that came in the LP groove modulations and that's per sé an advantage over a low compliance cartridges and other advantage of the HC is that tracks better at the inner grooves of the LP than a LC.

Low compliance could be in the range of 4cu to 9cu, medium compliance from 10cu to around 15-16cu and high compliance over this last compliance range.

 The ideal frequency resonance range between a cartridge and tonearm combination should be between: 8hz to 12hz for that cartridge could shows at its best.

If you buy the Safir for the Hayabusa probably you were out of that range what's not a good idea. For the Safir with a cartridge weigthing 9grs. you need that the cartridge has between 5cu to 7cu.

I never has the opportunity to listen the Safir and I never buy a tonearm with that kind of very high effective mass because that all mass will be what the cartridge cantilever/suspension will looks during play due that's a dynamic mass.

@rauliruegas 

What about the Hayabusa with an older SME IV.VI arm?

@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?
