Marcussix, when my wife and I made the change from the stock spikes to the Walker Audio Valid Points, we really weren't expecting much of a difference. What we heard surprised us -- the Valid Points made a significant difference that was immediately noticeable. And the result we heard was repeatable a few weeks later as we pulled them out and put them back in for a test of whether we might just be fooling ourselves. What we heard was improved clarity through the mid-range, greater delineation of the space around the the edges of instruments, and a decided clearing-up of some mid-bass muddiness I really hadn't paid much attention to until it was removed. I wouldn't put this in the same category as a component upgrade, but it was certainly another very meaningful 3-5% improvement in the overall clarity and resolution of our system. Needless to say, the Valid Points stayed as part of the system.
Another tweak we've made is the addition of a 2" Walker Audio Resonance Disc placed on the top of each of the Eidolon cabinets. The result here is far more subtle, but it is observable and repeatable. Play something with some sharp percussive attacks (like the piano on the "88 Basie Street" 45 rpm reissue), then place the discs and play again. What we hear is a noticeable tightening of the leading edge of the struck piano strings and a reduction in smearing. It's subtle, but it's another example of how paying attention to the details creates the magic.
