The AT-616 are better (in my opinion) because you don’t have to screw them in something, you can’t do that with GayaIn my opinion one of the advantages of the Gaia is the possibility of being able to screw them, in fact I used them in the Technics SH10B3 obsidian base to replace the original feet; the screw has the same pitch and there is no need to change anything.
Applied on the SH10b3 aesthetically they are a show but the improvement of the sound compared to the original feet is audible.
I prefer feet that screw rather than place the equipment on feet that cannot be fixed, just a carelessness by accidentally hitting the electronics and it could slip, damaging its own edge and the support surface of the furniture.
