I just use the spikes that come with the speakers. I did use their MoPads to get my center channel off of the entertainment center.
Is anyone else using MoPads? While I was ordering things I figured I'd get a set.
I don't think I can A/B quick enough to judge with my own ears, but when re-running the auto setup for my receiver after adding the QS8s today it now detects my center as "large", but without the MoPads it was "small". Actually I'm not even using the full MoPad, just the 4-degree wedge (I'd have to adjust the shelf height to keep the center from blocking the IR receiver on my TV and I just wanted to throw them in quickly). I instead put the full foam blocks under my Alesis, near field, studio monitors in my bedroom studio. They seem to produce more bass and are generally more clear than I ever remember.
Of course this all could be placebo...
