August, 2018 SFAS Event – Critical Mass Systems Racks and Footers
All in all this was another great SFAS event with engaged attendees who were able to experience the sonic qualities of an excellent system. Sincere thanks to Joe Hakim and his lovely wife, Debbie, for their hospitality and providing the venue for another great SFAS event.
Critical Mass SystemsTo: The San Francisco Audio SocietyI want to thank the esteemed members of the San Francisco Audio Society for attending my recent discussion about Critical Mass Systems and Center Stage audio footers. It was a pleasure to meet you and participate in your listening session. I especially want to thank Joe and Debbie Hakim for opening their beautiful home to my wife and me. Joe’s system is extraordinary. The level of playback he has achieved is world class. The last vinyl Beatles track played was so beautifully expressive and engaging I was nearly in tears. Experiencing an emotional connection with music is what it’s all about for me. Again, I want to apologize for my jet lag. There are two questions I could have answered better. If you don’t mind, I’ll try to address them here.1) What is a dual zone, 6-stage damping system in a MAXXUM?From the outside, the filter (shelf) appears to be “of-a-piece” but the internal structure consists of 8 to 12 channels through which vibration must travel upwards to the component. Each channel consists of 3 damping stages on either side of an elastomeric buffer. The elastomer lowers natural frequency and the damping stages systematically reduce vibration.Each damping stage is a sequence of hard and soft materials calculated to a thousandth of an inch that pushes certain frequencies to the fore and then converts them to heat. The lower zone’s 3 damping stages are equivalent to a 14-layer sandwich of 5 different damping materials specifically sequenced.The 3 damping stages in the upper zone are equivalent to a 22-layer sandwich of 6 different hard and soft materials. MAXXUM filters are “tuned” to the frame that supports them, so that the MAXXUM superstructure and its filters work as a unit to burn off vibration without degrading the performance of the components.2) What is the mathematical equation for the ideal border?Inside a component’s border are varying arrays of parts forming an electromechanical signal processing network. On the other side of the border is an intensely fluctuating mechanical energy field. Varying electromechanical pathways and differing forms of energy on both sides of the component’s border is the crux of the problem that drives the many physical embodiments of answers available today.Center Stage2, Stillpoints and Qpods are border interfaces designed to minimize electromechanical degradation. The A/B comparisons showed that materials, dimensions, and damping sequences impact sound. Which one of them provided the best border is yours to decide.Center Stage2 is an incredibly exciting product for me because it is the most powerful device I have ever designed at a generally accessible price point. In fact, I am so excited about the product that I am honored to extend a buy 3, get the 4th at no charge offer on all 3 Center Stage2 sizes until October 31st exclusively through Eigen Audio.
