I use finite elemente ceraballs. I used BDR, DH cones and some other staff. You can't even compare the ceraballs with the others.... They are so much better and brought a very significant improvment to my system. The difference is bigger then replacing cables. Especially clarity, ambience and stage is a jaw dropping improvment.
I use rack from the same manufacturer , Pagode Signature. But it didn't brought as much goodie as the feet. I highly recommend them to try.
