Steve,
I am in the process of simplifying my system and moving to less pieces.
This allows me to move away from the 5 component Sistrum rack that is out of the picture near my listening chair and move the gear to the floor between/slightly behind my speakers (see pic below).
Which products of yours do you recommend for the two pieces of gear:
  -  Vinnie Rossi LIO preamp/dac (weighs less than 25 pounds)
  -  Custom windows pc in a small case (weighs less than 10 pounds)
My room has a cement floor with carpet.
BTW, I am already using some of your products in my system: 
  -  Iso-Cups plus ebony balls under the amps in the picture below.  The Iso-Cups are on the wood block, which is on a small Sistrum platform.
  -  Titanium Giant Cone/Spike Decoupling Gliders under my Vandy 5A speakers
Regards,
George
