At RMAF 2008 I attended an eye opening Setup & Tuning Seminar conducted by HiFi+ (Roy Gregory) who I see posts to this forum. Since then I've installed Nordost Ti Pulsar Points under my pre-amp, amp, and SACD player and installed B&W spikes under my N802's. I've also added an Audience aR1p between a dedicated 20-amp wall socket and my PS Audio Quintet and a Nordost Quantum QX4 between the Quintet and my pre-amp. This has resulted in significant improvements in soundstage width and depth, imaging, and articulation.
My first question regards my B&W N802's. Are the B&W aluminum spikes mounted on "tendercups" to protect my wood floor sufficiently damping vibration? Or do I need to consider adding some type of speaker isolation platform? If speaker isolation platforms are effective, what specific platforms should I audition considering the 154 pound weight of each N802?
Secondly, I'm using a Billy Bags PRO-34 equipment rack for all my audio-video equipment. Given RG's warning at RMAF against using racks with steel columns and hard surface shelfs (in this case laminate), I'm considering replacing this rack. I know RG favors the Stillpoints and Finite Pagado racks, but since I'm already using Nordost Ti Pulsar Points under my pre-amp, amp, and QX4 for resonance control on this rack, will these very expensive racks significantly enhance vibration control?
