Aurios Pro Isolation Bearings + carbide balls

An all-time great isolation tool, these $600 bearings include two sets of the optional tungsten carbide balls ($50/set), to provide true isolation to your equipment. Stereo Times said:

"Given my sympathy for budget components, I’d love to say that the $600 PROs showed no major improvement over the original MIBs, the new 1.2’s, or the Symposium Roller Blocks. Simply put, there was NO contest. As good as these others are, the PROs outperformed them all by a significant margin.

The further gain in focus, clarity, and harmonic and timbral richness and naturalness held up at all volume and dynamic levels. Intelligibility of lyrics – a good test for midrange resolution and therefore a good indicator of the ability to recreate the heart of the music’s action - was significantly clearer than the other devices, and light years better than no isolation. Particularly noteworthy were the improvements in the melodic and pitch aspects of bass lines and in the dynamics and pace of upper-octave percussion. Harmony, the language of Western art music, became more explicit, a boon to those who (like me) do not play an instrument and thus are defined as musical illiterates. With the PROs, I could identify both the chords and the individual notes that make them up.

Small ensembles, whether jazz, classical, folk or rock, shone in greater relief: the performers’ interplay was easy to grasp. This not only allowed access to some string quartets that had eluded my appreciation in the past, but also allowed me to more fairly judge my preference among different interpretations. This illumination also transferred to large-scale orchestral works. Great jazz improvisation and flow appeared with an immediacy and intimacy that permitted me to feel I was participating in the music. Heady stuff! To say that I was awed would be to understate.

With the PROs, I found myself listening to music the way one does at a live concert. Musical satisfaction did not fall victim to listening fatigue. Conversely, background listening became impossible. Stripping my system of all the Aurios and reverting again to an "un-floated" state highlighted again just how much mental effort goes into listening through the distortions, muddiness and opacity of a non-isolated system. Hard work, draining, and a heavy interference to the music: fortunately now, thanks to the Aurios, also unnecessary."
