Bogiedr1- you have good equipment. If you want more warmth, have you thought about adding a subwoofer or 2?
As for your comment about MC, nobody takes his posts and advice seriously. In this post, MC recommended x number of springs, then after somebody suggested more, then MC increased the # needed. Maybe 10 springs would be better? Maybe 12? Why this is misinformation, any isolation product for a speaker has to be designed for the weight of each speaker. If you put a spring that's rated for a 20 lb speaker under a 200 lb speaker, the spring will be fully compressed and will not be beneficial. Same goes for any number of isolation products, make sure you purchase 1 that can handle the weight of the component
