I’ll try to further clarify my impressions of the the Omega mats in my system:
They certainly bring a substantial increase in resolution, transparency and clarity. What makes them so remarkable, though, is that this doesn't come at the expense of the life, energy and vitality of the music. Often, it seems, one of these sets of attributes is traded off for the other. If you've been in this hobby for a while, you've probably heard a system that has plenty of resolution, transparency and clarity, but is lacking in life, energy and vitality (or maybe vice versa). Having both at the same time, which, IMO, is the ultimate goal, can be quite elusive.
The addition of the Omega mats has greatly enhanced my system's ability to play music with both sets of attributes.
