I have Aurios Pros under my Kharma speakers on carpet, and have found it to be a big improvement in dynamics. I placed marble tile on the carpet first, and then the Aurios on the marble. I do not know the dynamics of why i works, but the speakers on carpet sounded muffled, even with the special spike stands that come with the Kharma speakers, which are very high quality spiked feet which directly attach to the base of the speakers.
