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

my wood floors are springy, isolation from that movement is beyond difficult, sadly made me part with my beloved Thorens TD124 which has a bearing very susceptible to vertical movement.

Both the JVC Plinth and Luxman Plinths have special technology, but neither can deal with my floors.

Each shelf of the rack is individually isolated via compressed rubber, the stands on top supporting the glass shelf have compressed rubber spacers top and bottom, and finally, a set of rubber/cork blocks are the high tech solution that solved it here.

Cork and Rubber Pads, I wrapped mine in black tape,

thorens with vacuum, keep all or sell some least favorite arm(s), note mine, Luxman, this one has a dust cover, many do not.

THAT dust cover is fine for down time, in between listening sessions, but it should be stored away somewhere when you’re using that TT. It’ll resonate like a drum.
