PeterA and I, on opposite sides of the country, and without knowing it, auditioned CS2 feet (me in my system, and Peter in a friend's) at roughly the same time. Interestingly (or not?), when we compared notes, our observations were nearly identical. As I recall, the two most noticeable traits imparted on the sound by CS2 feet had to do with soundstage depth compression and leading edge attack. This despite the components and racks in question being entirely different. Empirically, I observe the soundstage effect in general causally related to isolation which results in damping. That is, I can minimize or enhance this effect by adding or removing isolation and damping. Attack and tautness are a bit harder to pin down but are certainly enhanced by coupling to a (fairly inert) substrate, and affected by the particular method of doing so, e.g. captive bearing, free bearing in cup, etc., and by materials choice, e.g. wood, steel, aluminum, combinations thereof. In the end, it's very difficult to walk the line between isolating and coupling in order to extract the best of both worlds. It's even more difficult or perhaps impossible to produce a one-size-fits-all product that pulls it off universally. So, I don't think we should be arguing over semantics, e.g. "coloration". CS2 feet have a sound that I've heard in my system, in one other system, and then was validated by others during independent audition. But then so do steel plates, which I use although not under every component. I disagree that some combination of rubber O-rings allows the steel plate user to arrive at uncolored sound. No, they allow the user to tune the coloration to their particular preference. And it's ok to refer to the sound of footer products or of steel plates as a thumbprint or coloration. It's also accurate to do so. If it gets you to where you want the sound, then just be happy.
Brian, yes I think we have similar impressions of the effect of these footers on the sound in your system and in my friend's system. I think it is very difficult to claim a device, component, accessory, is tonally neutral or does not add a coloration to the sound. How would one go about proving this? Neutral or colorless compared to what? Alternative devices under direct comparison, perhaps, but what is the ultimate standard against which we judge this? I like to make direct comparisons when evaluating gear and changes to set up. But ultimately, I compare what I hear from my recordings in my system to my memories of live music. That is when I really know progress is being made.
Listeners to these footers describe the experience as being closer to live music, with a more enveloping sound. The sound comes to life and bursts forth breaking the "fourth dimension" of the plane of the speakers.
What I found interesting when auditioning these CS footers is that regardless of what type of component they supported, or the music being listened to, their removal created the same effect on the soundstage and sense of energy and life in the room. This was regardless of music genre, scale, or recording venue. It also seemed independent of recording quality.
I would ask if these impressions occur on all music or simply on the recordings that capture this kind of enveloping spatial information and energy. For me, the goal is about retaining the maximum amount of recorded information and presenting it through the system intact and uncorrupted. The result should be natural, convincing, and pleasing. This means that different recordings will tend to sound more different from each other when the system presents this information faithfully. Recordings should not sound more and more similar to each other having the same kind of enveloping room filling sound if that information is not inherent or embedded in the recording.
When we try something new, we can usually tell pretty quickly if it takes us closer or further away from our goal, whether it is our memory of live music or something else. I prefer closer, and as that distance gets shorter, I know I am making progress. We can all claim it is only for our own happiness and enjoyment, but there is also how we each think the sound compares to our individual references. I don't know what else there is.
The stainless steel plates need to be tuned, that is for sure. How colored they ultimately become is a matter of perspective and comparison to alternatives, and to one's reference sound.
