I’ve been an owner of two Sistrum racks with 3 platforms on each for about 8 years now. I may also be the only one to have RTS couplers clamping each component to its platform. Just setting a component on a Sistrum platform will immediately make it sound better in all ways than most other racks. The RTS couplers in addition cause almost the same amount of improvement as the Sistrum rack. They also don’t allow the component to tip if leaned on because of the 3 points it sits on with the Sistrum platform only supporting it. Audio Horizon makes the couplers now. The combination of the two things is very nice looking and allows one to locate the rack(s) between the speakers as long as they are also mostly behind them at the same time. The Sistrums don’t have a location problem like Jim Smith mentions in his book. Their is so much space for air and vibrations to travel without getting trapped by the back of a typical rack. The technology that has a quick draining of vibrations to the ground is another great reason for the superior SQ.
I had Robert Maicks cut my longer rods that hold the platforms in two so that it would sit lower, and thus be even less likely to affect the sound in a detrimental way. It also makes the rack more stable. I love these racks, the look, and the sound that results from their use. I use them for my 120 lb. Lenco TT, Modwright 5400 CD player, TRL DUDE 75 lb. preamp, phono preamp, and my mono amps. It all sounds fantastic. There are 8 tubes in use also.
