I am inclined to take Dave's advice, namely to put the waveguides on Star Sound Rhythm platforms with them on Audio Points. Yesterday I moved my H-Cat p-12 line stage from shelf 4 to shelf 1 on my Rhythm rack. I had always heard that the lowest shelf was best. It is absolutely correct! It is not subtle; it is dramatic.
I'm going to go to all two shelf Rhythms and going to put all waveguides on Audio points on the second shelf with the HFC waveguide power center on the bottom shelf. I must admit that I might find putting the waveguides on ceramic isolators might be more important. Unfortunately there are no ceramic cones like Audio Points or flat isolators that could go under the Cupeling cups of the Rhythm feet to keep static electric charges at bay while getting vibrations to earth. Reproducing music is such a pain in the ass. Were I to have a top .1% income of $6.5 million I would have a pop singer, a jazz group, and a symphonic orchestra available when I wanted to hear music. Of of course, I would need a well designed room to hear them properly. On my 60th birthday, my wife hired a small and good jazz group to play in our kitchen. It was great, but a kitchen is not a good location.
