I started off using Symposium Roller-blocks under my Accuphase DP-75V CD player. I had a problem leveling the Symposium shelf upon which it sat, so the bearings never centered exactly right on the Roller-blocks. I switched to the Aurios (1.0's, non-self centering) and I preferred the easier set-up and closed bearing system over the R.B's. Please note that your platform or shelf leveling must be "balls-on" when using either of these items. I have not had experience with the later versions of the Aurios which are supposed to be self-centering.
I picked up a set of Stillpoints with risers at the 2004 CES. After placing them under the Accuphase, I was shocked! The sound SUCKED! I lost all of the "air" and nuances of the mid & high frequency micro-dynamics. The Stillpoints went up for sale the next day!
Please note that both the Aurios and Roller-blocks are susceptible to cable and power cord "drag", and can easily lock up, pulled to the end of their free travel by the weight of the cords. Ganymedes are a superior design similar to the Aurios, but with a much greater range of bearing travel. They also work in the vertical as well as the horizontal plane for vibration absorption. And they will still work well if operating a few degrees off level. Alas, I have heard that the Ganymedes are now out of production!
