I replaced the hefty stock Focal spikes with Stillpoints Ultras, sat back, and was shocked by what I heard. With the Stillpoints, the soundstage opened up with greater width, depth, and bloom around images. The sound became even more detached from the loudspeakers, with a greater solidity of images between and around the Focals …
… The bass improved to a similar degree. The bottom end became tauter, better defined, and cleaner. The Stillpoints made the midbass a bit leaner, but more articulate. The improved midbass conferred greater clarity in the midrange, as well as in the bottom octave, where very low bass notes were more audible and defined once the midbass was better controlled. Bass dynamics were also improved; notes seemed to start and stop more quickly, giving the presentation greater dynamic agility and conveying more of the musicians’ dynamic expression.
Finally, replacing the stock spikes with Stillpoints make the background “blacker” and quieter, allowing greater clarity and resolution of very low-level information. Sounds that had been somewhat undifferentiated with the stock feet became vividly clear. For example, percussion instruments that produce a series of very fine transients (shakers and guiros, for examples) sounded much more real with the reduction in transient blurring. Moreover, it was much easier to identify exactly how the instrument produced its sound. All this added up to a more lifelike reproduction.
