Mingles, it's difficult to know what is causing your lack of air and spaciousness. Could be the table, arm/cartridge or table/arm/cartridge combo. My highly modded Thorens with modded Rega arm and Denon 103r has a similar lack of spaciousness compared to my VPI Scoutmaster. I'm still in the midst of voicing in this tt setup so I haven't come to any definite conclusions.
Your problem also could be with tt isolation, I just finished up some aluminum top plates for my DIY sandboxes, haven't listened to Thorens with this top plate yet. It did markedly increase air and spaciousness with the VPI so I expect it will do the same with Thorens.
The suggestion for MintLp is also right on. I previously aligned my cartridge on VPI with VPI jig and DB protractor, the MintLp was a nice improvement. I will eventually get around to this with the Thorens.
