@cxp - I recently ordered pucks for all my components and had a custom bamboo plinth made that carried the (2) SBOOSTER LPS & Nucleus+. I used Bronze pucks (4) for the plinth and asked the manufacturer of the bamboo (20in X 16in X 1.5in) plinth the weight and got 13.75lbs and that brought the puck weight close to the edge of optimal. However, I did not believe him after researching the density of bamboo planks. I determined the weight should come in at 10.5lbs. Long story short, 10.75lbs. These puck optimal weight per puck really matters. The good news is the plinth w/ component weight is right on the money. I just reconfigured my rack to use the pucks and have been waiting 3 weeks for them to come in. Plinth, DAC, DMP, PRE, and AMP. I also added a 0.625in (2.5in diameter) puck that will fit under the AMP puck to allow the XLR cable to be closer to the Preamp. It is not stretched; however, the closer I can make the connection, the better.
