hi Tom,
Excellent timing, I have been working on isolation under the spikes of the outriggers this week.
So far the solution I have is making a major improvement, I will get more info and pics up in the next couple of weeks.
At this time my testing has been at the shop/showroom which is carpet on slab. With the isolation I am making, it has more bass and more definition & detail as well as improved imaging.

more info soon
thanks,
lou
