Never heard either one, but I can vouch for using two tonearms. As for isolation, get a minus K platform: costs 2-4k.
SME Model 20/12 versus TechDas AirForce V or Suggestions for a 2 tonearm TT
I have a Model 20/12 TT with a 312S tonearm. Some time ago ( a long time ago, in fact) I ordered a Schroeder CB-L tonearm. However, as Franck Schroder is very busy, it took a long time to fulfill the order.
in the mean time, as I didn’t believe that I would get my CB tonearm anymore, I had the chance to buy a Graham Phantom III 12” tonearm. This week, I got the good news that finally my tonearm is ready. So I am faced with having 2 top notch tonearms to use, having a TT which accepts only one.
My audio dealer offered me an almost irrefutable business to exchange the SME 20/12 with its 312 tonearm for a AirForce V TT, which allows for two or more TA
The V has more technology but is not well isolated as the SME 20 I wonder what is your opinion about the business and if anyone has listened to both tables with same tonearm and cartridge to compare

The V would have to go on a MinusK platform which is another 5K. I do not care much for TechDas products. I think your SME is a better turntable. My first choice would be to sell the Graham and the 312S, mount the CB and you will never look back. If you have to do two arms then a Dohmann Helix 1 is the best way to go. The poor man's version is a Kuzma Stabi R on a MinusK platform. Being a sadomasochist I am thinking about taking a Sota Millenium, removing it's suspension and placing it on a MinusK platform so I can mount two arms, a Reed 5T and a Schroder LT. I am a sucker for vacuum clamping. A turntable without adequate isolation is not an option. |
I went for Vintage Direct Drive Quartz Locked on composite 7 layer deck JVC TT81 spinner on JVC Plinth CL-P2 (two removable armboards) then I added a 3rd arm, had to be a very compact Mission/Jelco to fit within the dust cover Notice, I added a deeper glass shelf as the Plinth is very deep look here if image is distorted I helped my friend put together a Luxman PD444 Two Arm Table, it is wider, not deeper like mine. Elegant simplicity with terrific technology
The Luxman includes an A/B switch so only one phono cable out. Mine, 3 phono cables to a SUT with 3 selectable inputs. |
@elliottbnewcombjr and neither turntable is adequately isolated. |
If you do extend your investigation to A/B Comparisons. I f carried out at the Dealers do make sure both TT's are demo'd on identical mounting along with identical supporting Audio Devices downstream. The identical Cart' set up may be more difficult to achieve. If a home demo' can be arranged, this will be even better for your deliberations to follow. The more effort put into discovering methods that can be adopted to mount a TT, with the intent to decrease ambient energies being easily transferring to the Styli. Creates a TT, that can become unrecognisable to when it has been used on a Mount that has not been considered to substantially reduce / resolve the transferral of ambient energies.
