I don't hear any difference in sound using the Auralax with the Mofi. It sound the same as it did without the platform. I first tried some inexpensive isolation blocks, they helped a little with the footfall problem, but I noticed a slight loss of transparency. I have it sitting on a Standesign rack with spikes on the bottom, and the top shelf is spiked too, for a turntable. Yes, I'm enjoying it. Slaw, if you have any advice about better isolation, let me know, but for now it's ok.
